Oh such a frustrating challenge. I first noticed it when I was a just few short of 900 caches. At the time I was mainly finding ? caches, I had a quick look at my stats and found that I only had three different icons at the relevant milestones. I had been caching for more than three years so at that rate it would be at least three years before I could qualify - that seemed like ages so I decided to ignore it and find another ? cache for my 900th.
Big mistake. A few months later I changed my mind but by then the earliest I could qualify was at 3000, thus adding another three years to my quest. I made sure that I found a webcam for the 1000 milestone (while doing the "11 icons in 11 hours" at the Geolympix 2012). Two years and some months later I was ready for my 2000 so arranged an event for that.
One more milestone to go. I was hoping this would be a Wherigo - the GIM Reindeer Games. Our first attempt failed because there was a football game being played where it wanted us to chase Dasher. The second attempt got past that but failed at the next hurdle - our GPSr couldn't play the MP3 for Dancer and Prancer. Heartily sick of Christmas by then I decided to get an Earthcache instead, and thence I qualified for this challenge.
Here are my six qualifying milestones:
1) Trad - Travel Bug Hotel Any Rooms Sir?
5) Multi - Wellington's Booty
200) Puzzle - Dorking by Pictures: Go West Young Man
1000) Webcam - Banbury Cross Webcam
2000) Event - Farnham F2K Event
3000) Earthcache - The Hanwell Sarsen Stone
Today I had been at the CITO at Warnham Nature Reserve, so I decided to pick up this cache as it wasn't that far away. No problems finding it - a cute cache.
