In the early days of the program, the bike racks were only moderately popular. People were still getting used to the idea of borrowing a bike for a short time at one location, riding it, and then leaving it in another location. Perhaps another reason that people were initially reluctant to use the bike racks is that they were introduced during a very hot week, at the beginning of summer. As discussed above, when you ride a bicycle, you often sweat. This is particularly true when the temperature is high, because your body produces sweat as a way of trying to keep your body cool. If your body gets too hot, you can get sick, so it's in your body's interest to maintain a constant temperature.
