Mountain.. Climbing.. Not wanting to go.. I'll show that mountain who's boss, I'll kick it's ass even though it's raining and stuff.. I don't care, mountain prepare yourself!
More like hiking but maybe some climbing. Equipment depends on the situation, for hiking all that is important are the clothes but when it comes to longer trips you have to take food and if you're traveling alone maybe even gps. But for a decent hike, you shouldn't need much. Just good clothing.
