About two miles into my commute, I ride down a steep hill on Park Terrace Drive. The top of the hill was socked in with a heavy fog this morning. Riding down this hill in the morning is a real eye-opener, especially when it's only 35 degrees. I can go as fast as 38 miles per hour during the descent. At the bottom, I hit an s-curve - a hard right followed immediately by a hard left - to make things even more interesting. This morning's fog added a new feature: I couldn't see more than a few feet beyond my front wheel. Need less to say, it was an interesting way to start the day.
