I just started biking to the commuter train station (it's just the beginning of a 90 min one-way). It's 3.25 miles and I do it in about 16-18 minutes (exact minutes matter when you're catching a train). The train ride gives me a chance to air out before work, so the summer weather hasn't been too bad. Chicago winter should be fun :).
