Do you live near any mountainsJ?
Nearest one is a 40 minute drive away! always fancied going mountaineering, which describes the sport of climbing up mountains
I'm surrounded by them and in a rural area. So it's there, might as well use it 
One day before I die Id like to climb mount Everest, Earths highest mountain above sea level! maybe not to the top though..
That does seem to be dangerous sometimes. Mine are lots of trees and different plants and rocks . Good exercise too.
Yes very dangerous if you dont have the experience, athletic ability or technical knowledge to remain safe.
