A song that always picks me up and I always end up singing along with is "No Rain" by Blind Melon. Another song that always has an affect on me is "November Rain" by Guns N Roses. Ah, to be a young, depressed college student again.
Also as a kid, I climbed Mt. Monadnock, 3165 feet. My appreciation for "mountains" has changed since I moved west, though, living in the shadows of Mt. Hood (11,237 feet) in the Portland-area and Mt. Rainier (14,410 feet) in the Seattle-area.
