Micros can be nasty, but I've noticed that you will find that good and responsible users let you know.
A good example is GC1ZMT5 which is located inside a storm drain that has seen some "interesting" activity in the past. The storm drain is actually a pitch black tunnel that you walk into and the container is a about the size of a cut off section of drinking straw. So not only is is somewhat dangerous, but also insanely hard to find.
Yet it is an absolute blast and takes you to an interesting place. Like everyone above has said, if you don't think the cache is worth the time, move on. Some people have a more adventurous spirit.
We've even climbed to the tops of trees to get caches...extending over rivers. Yet some of our favorites are nice and easy lock-n-locks.
To each their own.
