BASE

The title is an acronym and stands for building, antenna, span, and earth. Contemplating on how to fill a list of things that one must do before whatever happens to prohibit doing, I found out that people can jump from building, antenna, span, and earth structures. Currently, I am wondering how time and cost intensive are parachute gliding lessons? It seems if you want to do this more than once, you have to know the basics. Actually, these "basics" are more than 2000 conventional parachute drops.
