I have never posted on these forums on the past (despite finding benchmarks for years), but felt that this topic was important enough to speak up.
I can remember a few more users not listed above that have significant, detailed logs (1000+):
CallawayMT
AZcachemeister
southpawaz
2/3 Marine
I can also recall some users that have fewer logs (in the hundreds), but collected clear, methodical (and useful) data:
bvrballs
heelerpack - Includes detailed logs of stations in very remote parts of Wyoming that are seldom visited.
I also fall into this latter category with only around 250-300 logs (all of stations on the island of Oahu, HI), but with detailed descriptions and photos.
