Haven't bike commuted in...10 years?

Today I changed that. Drove down to a park on the riverside MUP and commuted the 6 and a half miles from there. I used a hard tail Haro mountain bike, only commuter mod is a front handlebar bag; still on knobbies. I'd like to have something more upright and with less rolling resistance (and fenders!) but for now this will be ok. If I do it much more I'll either mod the bike or get something different.
