I learned to climb because I'm a "spinner" and was pushing a high low-gear. Only thing left was technique. Only dumb thing is that as I race up hills (because that's just the speed I have to go to be successful), I'm sure other people pushing granny gears look at me and think I'm some kind of newbie racer wannabe. Oh well.
Of course, having said that, the climbing around here in Wichita, KS is nothing like CA or MI, so I'm sure to be in for a rude awakening at some point.
