I will reply in this thread as I did in the other: There may be quite a few of these D/T grid challenges out there, but before you go for any of them, make sure that you have met the challenge EXACTLY as it is listed on the cache page for each. Some may have other requirements in addition to just getting the 81 different D/T combinations.
If you want a real challenge, check out the original “fizzy” challenge in Wisconsin placed over six years ago by Trekkin’ and Birdin’. GC1GVN6 Back then, you had to seek out the D/T combinations you were lacking… no D/T power trails like there are now that practically hand you your set of 81 on a platter. And to keep the original Wisconsin challenge pure, T&B put a placement date requirement that all of your 81 qualifying caches must have been placed before the publish date of their challenge cache (no new caches placed “just” to meet a certain D/T combination)… which means that when you are checking on your D/T grid, you must have at least one find in each cell of a cache that was placed on or before October 3, 2008. There is no restriction as to when you made your finds, just when the caches were placed. The COs also require a sampling of the major cache types to be in your grid somewhere, too. Only 22 cachers have met this tough challenge in all this time.
Trekkin’ anad Birdin’ also “walk the walk”, having accomplished the well-rounded feat themselves not once, not twice, but… ??? At least 25 times, I think. (Please enlighten us with a number here, T&B.) As for us, we still have some of the tougher combinations to become well-rounded at all, but at one point we did check, and only a few of our filled grid cells did NOT have qualifiers for “The “Cheesy” Well Rounded Cacher” challenge. But we’re not getting any younger, so we’ll just stick to our lofty goal of making one find (that is FIND, not FTF) per month and leave it at that. 😉
