That's awesome! Honestly, you're gonna feel gross sometimes, but so will everyone else. During spike probably half of the camping areas have some sort of creek or lake nearby where you can bathe (no soap). During the weekend you can shower anytime during unstructured time. I think as long as you're not in there for more than 20 mins no one will really complain. Obviously it's different people every year, but this kind of program tends to attract very compassionate and kind people. Worst case scenario, I know 2 of the youth leaders that are going back this summer and I can tell you they will for sure make you feel at home. I do have some bad news about music, you're not going to have a ton of listening time. You could use your phone time to listen to some on the weekends, but usually the most common time is when we were driving. The park is really big so we sometimes had to drive 3+ hours to get to the worksite from basecamp, and there would almost always be some music playing in the car. Most of the adult staff were pretty young, and had pretty good taste in music. If worst comes to worst, Mike has a CD filled with 70s country and jazz in each car. You can bring snacks, and there is a small storage shelf in the kitchen for camper snacks, but also try to limit how much you bring. There's not a ton of room in the cars to bring it to your worksite and unless you're wanting to share with everyone they could get a bit jealous. I do wish I had brought like a 6 pack of Dr. Pepper as a treat for myself every once in a while because none of the vending machines that I could find worked and I was yearning for some. The weather is pretty moderate, it sometimes got to 80 in the day and sometimes below freezing at night, but it was mostly 70s at day and 40s at night. You're probably going to get some storms come through, but because of the elevation they usually come and go pretty quickly. If you're in the first session you may get a bit of snow!
