Good suggestions, thanks. My wife and I are in our early 50s with a teenage son, so we are pretty open to different things to do. St. Augustine sounds good, we thought about visiting the Devil's Millhopper sinkhole in Gainesville (went there as a kid). St. Augustine is definitely on our agenda. I thought about dropping down to Ocala from Gainesville for the Silver Springs thing, I have never been there before. Museums sound good if they are interesting ones. I also thought about stopping off a the Stephen Foster State Park, not sure exactly where it is. I remember camping near there as a kid, but we aren't planning to do any camping this time. If there are rental bikes available at the Park, that might be fun. We have a week, and are not in any big hurry or into any extreme adventure stuff, just wanted to get reacquainted with the area and the culture mainly. More ideas are welcome!
