Our cache GC1DJ6Q “Miss’ Mathematical Mystery Tour – 05” hasn’t been found since last 20th February – so if no one finds it in the next two months it will become eligible. Similarly MMMT – 02 will become eligible in March. I think the problem is not so much how to find eligible caches as how to find ones that one hasn’t done – especially when you’ve found several thousand caches! My method of finding suitable ones was to look at nearest caches that we hadn’t found from our profile and trawl through looking at the right hand column for ones that hadn’t been found since 2010. It takes time but is not an impossible task!
