A very fun activity involving going up and down walls repeatedly, in as difficult a manner as possible. Actually, ideally it involves going up and down actual rocks or other natural formations, but you work with what you have. You know you've had a good day climbing when doing the simplest things, like opening the door to your room, is hard. Some would say RockClimbing
is slightly masochistic, and they're probably right.
Indoor RockClimbing, fun though it may be, is definitely an AntiColorBlindness? experience.
People who enjoy RockClimbing:
CLoA could probably be applied to RockClimbing, but it would be hard, since difficulty levels are fuzzily defined, and courses differ from gym to gym.
