I rode to work today on Citi Bike, and my wife is picking me up. From here, we're going to our weekend home. I normally keep a helmet at each home, and I didn't want to lug the helmet around all weekend and back to the city. My route is only on a MUP except for two very short distances, so it's safe. It was a nice break from the helmet. I think I'm too strict about wearing a helmet almost every time.
