Why do we"my nearsighted brother and I", do it. First and foremost it brings us closer together. Second the thrill of the hunt, something primal in mankind that a lot of us do not want to admit to. Third the exercise, I've done things geocaching that I never thought I was capable of. Fourth learning about the land we call America I've learned a lot of history while caching, not the big events we all know of,but the little things that are gone now and will never return. I've been to a jail in my state that was erected in 1897 and used into the 1980s. Finally its just plain FUN !!
