There's a cacher here in S. Oregon who is an ace at creating micro caches. I'm not sure whether he thinks these up himself, or whether he's gotten his ideas from other places (he's found a whole bunch of caches), but being new at this game, I can tell you that he has made my learning curve very steep, and I feel very gratified when I find one of his micros. He loves rocks and camo tape! I think its important for Geocaching to have large containers so that kids can have fun with the goodies and feel like they're really on a hunt for treasure, but lets face it, us oldsters don't need dollar store stuff, its all about the challenge, and with the GPSr's available today, getting on top of a cache is pretty easy. But once you're there, let the micro fun begin!
