Chillin' in St. Augustine

We came to St. Augustine Friday because they threw us out of Ft. Clinch SP. Actually they were booked full for the weekend, so we came here. It is a KOA within less than a mile from the Ocean in St. Augustine, a couple hours south of where we were before. We'll be here til Mon AM because we have an oil change scheduled for the RV Monday noon, and now we have a problem with the Miata. All of a sudden today, the brake pedal goes all the way to the floor. I believe we'll have to replace the master cylinder, but can't get anyone to work on it till Monday AM. We'd like to go farther south since the forecast here is for temps in the high 60s and also rain several days this next week. But we haven't made any specific plans yet.
