Nice! And 4 miles out isn't too bad. I bike commute all year & 4 miles is about the commute I have now...It's not bad but it's usually enough to keep me from using the university library for studying in the winter. I've drawn this imaginary 4-mile circle around the medical center and said "I will not live outside of this," but I'm still not sure what to do about things on the edge of my circle. I'm talking to some folks about a cheap room ($475!!!) in the Central District, but I am still wondering if I should hold out for something slightly closer in.
But then again, a longer commute means I can never say I'm too busy for exercise since I have to do it to get to school.
