I bike to the gym. Its 2.5 miles on heavy-traffic roads, 3.8 on back roads. It takes me about 12 minutes as opposed to 4 in the car. As a previous poster noted, it just seems wrong to hop in the car and drive to the gym to exercise. On the weekends there are always a few other bikes in the bike rack, but at 5:30am I'm always the only one.

I really want to get a trailer and try grocery shopping by bike, but I usually take one of the kids with me to the grocery store. I would bike to many more places if not for the kids (ages 2 and 5). I know I can put them in the trailer, but to go just about anywhere from my house you have to travel a major road with high speed traffic. The shoulders are wide and usually clean, and I feel totally safe riding that road myself, but the thought of riding that road with the kids just makes me waaaayyy too nervous.
