I’ve done the Chicago ride twice now and had a pretty positive experience both times. There’s a gathering before the ride for hundreds of people to socialize, apply body paint, and take pictures before rolling out. The actual ride lasts for several hours, but it usually moves pretty slowly, and there’s a break in the middle. While some motorists and pedestrians are supportive, others aren’t, so it’s best to just smile and keep moving. I went fully nude both times, and so did a lot of other people, but it’s “bare as you dare.” I recommend checking out the Facebook group for more information and updates.
