We had made our caches, identified the route and knew roughly where we were going to place them. We knew we wanted to make a mini series but were still debating on route what the name of the series should be. Then we arrived at our first hiding place - and an idea started to form - by the second GZ it had been verified! This is a series of Useless Items. With the final cache being the most useless items of all!
After suffering a power of slagging from the aforementioned "gentlemen" after my birthday about my age clearly some form of retribution was required. NO doubt Mrs P and Mrs SP will have some comments on just how useless these particular items are!! :-D ;-) 
With thanks to H fae Team Clova for the Photoshopping!
