I agree on the meds. Know the area you are in and where the nearest hospital/clinic is ahead of time. Perhaps have some system of easy identification of your campsite if medical help is looking for you.
I would also say that in my experience you will be participating in an activity that has a lot of good like minded people. Say hi to people, some will talk to you some wont. Everyone is different.
If you dont want to wave and talk, turn your lawn chair way from the area people are walking by. Make plans to cook your favorite stuff, bird watch, whittle a walking stick, bring a book, go hiking, read the information board to see what the area is known for. Good luck to you.
