I rode during lunch today. I've discovered that from the parking lot at work, around the local fairgrounds twice and back again nets 5.1 miles... I've done that every day this week, except today a coworker went with me and we just went around the midway and parking lot area, as it's been about 20 years since he had been on a bike. Probably doesn't sound like much, but it's been about 9 years since I've been out on 2 wheels myself.
