I've had state park annual passes for a couple of years & give them as Christmas gifts. The family pass gets everybody in the car into any park in the state. With the individual pass, everybody after the driver pays $1 (although I've had friendly rangers wave me through if I only had kids with me). If you're going to ride a lot at Alafia, or if you like to go to state parks around the state, you'll come out ahead if you go into a park more than 8 or 9 times a year. I also look at it as a good way to support the state park system. Buy the pass.
