I'm new to caching, very new. I like both types. The larger caches are great for my kids because they are usually easier to find. My kids are 6 and 8 and have fun going on caches with me. With that being said, however, I've found that when we search for micro's-particularly in the woods, they get frustrated-mostly because their age level.
The only time micro's frustrate me is when they become completely buried in leaves in fall. I'm not about to bring a rake to go caching. Also, like if it hidden in a nut or pine cone AND THERE ARE HUNDREDS OF THEM AROUND that is ridiculous in my opinion. If it is a pine cone attached to a birch or oak tree (or under one) that is cool. Also, micros that are literally buried three feet UNDER a farmers rock wall is a bit much, not to mention people take these walls apart and don't put the rocks back.
So yes, I like them in most cases but not all.
