I just saw this thread... I signed up last year, but have never gone on a ride here in FL. I tried to ask how it works and I received a one line response that said "just show up". I was asking what should be worn (long sleves on bases...) what the requirements are for flag bikes (I have a mount that can hold two large flags mounted to solid 5/8" steel round bar stock) I don't know anyone here in SW FL who attends the events, however I have seen several right in Sarasota, FL...
