A friend of mine organizes an annual bike ride in Somerville MA, called the Illuminations Ride, where several hundred bikes group up (with a cop bike escort!) and go tour the craziest houses. There are trolleys doing it too, but one year he and his wife said "this route is so short, we should make it a bike ride too!" The wife and I were both on cargo bikes, I had a friend's kid (we were also babysitting that evening) on the front of my bike, and the Mrs had our daughter and the other little girl in the big cargo "box bike," under a clear cover and snuggled into a comforter / pillows.
So we were at the very back of the pack, which meant VERY little time to take any photos. I did what I could without trying very hard.
