Deepdiggingmole (212719)
Deepdiggingmole (or ddm) has been a user of PGC since 2014 - though as a finder of caches he began that way back in 2004. ddm is a fan of challenge caches and enjoys the variety that there are out there and the extra spin that challenge caches have given the game of geocaching. ddm joined the team of moderators who vote on caches that are placed on the challenge exception list and is quite vocal in the exception list forum ;-)
