I am new to geocaching. Started in April, but made my #100 find today! If I go to a cache and have to search around in front of muggles, I usually won't do that cache. I still haven't totally got the hang of using my GPS and I need time to wander around and don't want anyone watching me. I, too, wonder about those caches hidden on guard rails along the road, the ones in cemeteries (my favorites because no one wonders why you are walking around there)and the ones in local parks in town. Did they ask for permission to place those?
