PLEASE NOTE: These caches were originally all letterboxes, with stamps that I personally painstakingly made. Unfortunately, they have proven quite popular, and with that comes muggling. Apparently a number of the stamps have gone missing, and as some have complained about this, and I haven't the time to go and check all 100+ of them on a regular basis, I will be converting them to Traditional caches as needed.
It pains me to make this decision, but it must be done. I recognize that with a powertrail, caches are bound to go missing (that is the nature of the beast), and I appreciate that many of you have helped out by bringing along spares. However, your average cacher does NOT carry around spare stamps, and even if you did, it wouldn't be the one that I originally and personally made for the cache.
So, I am asking for your help: please let me know in your logs which ones are indeed missing their stamps, and I will be changing them to Traditionals (the alternative is archival, unfortunately). Thanks for your assistance in this endeavor, and thanks for supporting this series. I am glad that I spent the many hours needed to create these. However, I cannot justify consistently having to make and then replace all the stamps, due to time constraints.
Sincerely, the CO, josephaw

First off, let me thank you for finding this geocache! I hope you enjoyed the experience of finding it as much as I enjoyed creating and hiding all of these letterbox caches.
This is just one of many such caches in my Dr Who Letterbox Series, made with the help and inspiration of friends. As a Letterbox cache, please leave the stamp for others to see and use, thanks! Each cache has a unique stamp, so bring an inkpad and collect them all! Have fun, and be safe!

"Fear Her" is the eleventh episode of the second series of the British science fiction/fantasy series Doctor Who, first broadcast on BBC One on 24 June 2006. It was written byMatthew Graham and directed by Euros Lyn.
The episode takes part on the day of the opening ceremony of the 2012 Summer Olympics in London, almost exclusively on a fictitious cul-de-sac named after the British athlete Kelly Holmes. While originally only intending to visit the ceremony, alien time traveller the Doctor (David Tennant) and his companion Rose Tyler (Billie Piper) investigate Chloe Webber (Abisola Agbaje), who has the ability to make people disappear by drawing them.
The episode was brought in to be a low-budget replacement for a script by Stephen Fry that had been pushed back, and was filmed mainly in the Tremorfa area of Cardiff at a housing estate. Graham was asked to write an episode primarily for children which would soften the much darker finale that would be broadcast after. The episode was watched by 7.14 million viewers in the UK, and was given an Appreciation Index of 83. Though Graham received letters from children who enjoyed the episode, it did not generate a positive response from adult fans and critics.
Plot
The TARDIS materialises on the day of the opening ceremony of the 2012 Olympic Games. The neighbourhood is preparing for the passing of the Olympic torch bearer, but the mood has been dampened by the disappearances of several children in the prior week. A council worker named Kel also mentions that cars have been breaking down momentarily for the same period. The Doctor and Rose investigate and realise that the source of the problems is a solitary 12-year old girl named Chloe Webber. She has the unique ability to cause people to disappear by drawing them. The Doctor hypnotises Chloe and finds out that she is possessed by an immature Isolus, an alien life-form that travels through space with a family of billions. This particular Isolus crashed its pod to Earth due to a solar flare. The Isolus relates to and befriends Chloe, who had a troubled childhood. The Isolus has also caused Chloe to draw a life-sized, exaggerated figure of her late father, who it is strongly implied abused Chloe when he was alive.
The Doctor explains that if they can find the Isolus pod and provide it power the alien will leave Chloe. A frantic Chloe draws the TARDIS and the Doctor, trapping them both in one of her sketches and forcing Rose to try to find the pod herself. She rationalises that the pod is located on the hottest spot on the street, a patch of freshly laid tar, and is able to dig it up. Meanwhile Chloe has caused the entire crowd at the Olympic stadium to disappear and now is set on making everyone in the world disappear. Rose tries to find out how to power the pod, and uses visual indications from the Doctor's picture to understand that the pod needs heat mixed with emotion. Rose throws the pod towards the Olympic Torch - a symbol of hope, courage, and love - as it passes down the street. The missing children and the crowd at the Olympics reappear, and Rose realises that the drawing Chloe had made of her father will similarly come to life. Rose and Chloe's mother are able to calm Chloe by singing the Kookaburra song, causing the unseen monster - having fed off of Chloe's emotions and fears - to disappear.
As the torch bearer approaches the Olympic Stadium he collapses, and the Doctor promptly and suddenly appears, picks up the torch, and completes the run to light the Olympic Flame. The heat of the flame and the emotion of the crowd power the pod, allowing the Isolus to leave Chloe and return home. The Doctor and Rose walk off to watch the games, and Rose remarks that nothing will ever split the two of them up. The Doctor becomes uneasy and muses that a storm is approaching.
Continuity
Torchwood is again mentioned, by commentator Huw Edwards after the Olympic crowd disappears.[1] The Doctor again invokes the Shadow Proclamation, the intergalactic police force first mentioned in "Rose".[2] The Doctor mentions that his dislike of cats stems from being "threatened by one in a nun's wimple", a reference to the events of "New Earth".[3] In a bit of non-series continuity, The Doctor asks Chloe to identify a Vulcan salute, then uses a Vulcan mind meld to put Chloe into a trance that allows communication with the Isolus within her.
