There are quite a few hams on this board.
I would encourage everyone to get their Technician licenses. A buddy of mine who was into climbing was the one who first encouraged me to get my license. He has used his 2m/440 HT for emergency and non-emergency communications several times while out climbing.
Other radio services such as FRS, GMRS, MURS and CB will probably be useful as well, and each has its advantages and disadvantages. I have radios covering all of them, so I use what's appropriate for any given conditions.
Good luck!
