A friend of mine in college worked the graveyard shift at UPS moving their boxes all night. He commuted on his bike about 20 miles round trip. He didn't have a choice, so he learned to suck it up and got hela-buff and in shape pretty fast. Just stick to the main roads for now and make sure you're visable. Riding at night is a blast! You'll learn what areas you can ride in and maybe find new secret ways home once your comfortable with it.
