My commute is to my college, three times a week; 15 miles one-way, or 10 miles one-way if I take the bus. It's an entirely urban route until I get to the halfway point. The roads are mostly comprised of small rolling hills, but I do have to get past some steeper hills that are a quarter-mile long. I also have to keep to the shoulder on the interstate for a small distance (<1 mile), but aside from that -- it's a nice commute.

I've been bike commuting since last year, and I'm car-free. I've just been hating the heat, but thankfully Summer is almost over.
