Do you still have your first real MTB?
I gave my Trek 820 to my sister about 10 yrs ago and I've been thinking about buying her a new one for trade so I can get my old one back for memorys sake. I'd use it for a commuter.
It'd be kinda cool to deck out my old 820 with all 2006 components and keep the orig. frame and fork for the heck'uv'it. I don't have that kinda cash layin' around though.
