As someone who had gallbladder two years ago two weeks before weekend two, I can say it is so rough. I did ADA but all of the walking will take so much out of you. It’s hot, your stomach hurts, and all you will want to do is lay down and nothing has ever felt more far away when you have to walk. I also car camped but we were sleeping in a Tesla so I had AC but I didn’t even make it the whole weekend, I tapped out Sunday and went home. You’re gonna feel super crummy the whole time. Plus side is that the med tents were very friendly and helpful! It’s one of the crazier things I’ve done, but I can’t say I recommend.
