Out and about with my good mate WhiteFriar picking up, even for us, an eclectic mixture of caches! Perfect caching weather throughout, dry and nicely warm.
This has been on my "to do" list ever since it came out but it was only in the last couple of weeks or so that I started to make a concentrated effort to sort out the qualification. After about a three hour effort we finally cracked "Prosniper's Cryptex Quest" http://coord.info/GC2Q6ZK earlier in the day and this completed the qualification. Finding the cache itself, thankfully, proved a lot easier. See my web page http://www.15ddv.me.uk/geo/chal/hard_puzzle_challenge.html for a list of qualifying caches (done by by WhiteFriar as well).
