Even if you camp at Alafia,night rides are not legal. The trails are only open while the park is open unless you have a Beat the Heat pass then you can go in early but not with lights. A couple people were going in early with lights last year, one of them got hurt.If your caught this year they are going to warn you once (maybe), the next time your out. They have told me they are also going to start checking to make sure everyone who goes in early has a pass, if not you will be going home. Just a little FYI.
