We've been asked to set up a set of experiences wherein a girl scout troop can obtain their geocaching patches. We'd like to set and publish a couple of caches on a trail that's been created on school grounds. I thought I'd read a rule somewhere that says you cannot place a cache on school property, but at the same time we've found many caches on trail systems that are on school grounds. We've gotten permission from the district superintendent, but I wanted to see what the caching community (especially TAT) thought about it. Thanks!
