So out of all those miles, how many are bike miles? I know that what-cha-ma-callit folding bike allows for conveniant train access, but I could never imagine riding a bike like that for any long distance! Can a normal light weight road bike go on the train?

Godspeed to you - that's great commuting like that. I used to commute, but my job requires constantly picking up (construction related) material to jobsites , and I often need to take my pug with me on the road so, not only am I in the car, but it's a gas-guzzling wagon, no less! But yesterday, not wanting to lose the parking spot in front of my house, I jumped on the bike. I must remember in those all too infrequent, (or maybe not so infrequent times) that it's important to opt for the bike instead of the car - LAZY LAZY LAZY!!! And it sure felt good to be back on the commuter bike for once!
