ZB has wrote exactly what I would've.
I just finished thinning the herd down to four. I kept two road bikes for sentimental reasons, one which I do regulary ride, the other for a rain bike (Yeah, that's showing the love!) and my triple equipped bike for centurys, for when my knee acts up and for the Hill Country. The mountain bike is really the do-it-all bicycle with a change of tires and a dampening adjustment to the front fork.
