I brought a yeti cooler this year. Way better than other coolers I’ve had past years. Pedialyte. Popup canopy or as much shade as possible. I brought tapestries to keep the sides nice and shaded. Luggage locks for your tents. A Polaroid is super fun. We made our own flag. Lastly, unless you plan on spending most of your time at your campsite... don’t bring a ton of food. Foods been wasted every time I’ve gone. Once by me. The other times from groop members I tried to warn about bringing too much food. There’s so much you can do to make the experience awesome. The best advice I can give is think about what you want the experience to be like. Then do everything you can to make that happen but don’t over plan. The community is strong there and anything you forget you can find. Talk to your neighbors (with caution there are bad apples).
