If you plan to take advantage of the free entrance into museums this weekend, you will need to go here and print out the admission card. It is good for 1 adult and a guest. As far as getting into the Fort here in St. Augustine, I called and they said you don't need to bring anything, the video will be played every 15 minutes and they will have the canon firing also on Saturday.

Fun, FREE weekend here in St. Augustine!! Lots of other parks/museums also participating so call and ask the ones in your area~
