One more thing came to mind in regards to things to do while in Florida.
On February 12th the previously and numerously mentioned Racing's North Turn restaurant will sponsor and host the North Turn Legends Beach Parade. This parade is on the beach and consists of racecars that competed in the old beach/road course races held from 1935 through 1958. We've attended this event several time over the years and it is well worth the effort. I can't stress enough for you to get there EARLY. The restaurant will be serving breakfast starting at 8 AM.
Given that you are obviously a race fan and this is a very cool event for a race fan that draws a big crowd. I would recommend taking this in if at all possible.
