My ride home is down a long (about a mile), somewhat steep hill. People ask me why I go down the main boulevard with heavy traffic rather than the bike lane just one block north. It's because the BLVD has a median so that the opportunities for left turns in front of me are a lot less. It's pretty rad that you've got a computer to keep you company in there. You'll get better, and be more awesomer for this experience. Hang in there.
