I got the last site available and felt so lucky! Even the park ranger said I must be lucky lol. There is a sanitation agent who comes to clean/remove trash every day but you can opt out of it during your stay if you let them know. Park rangers also check in with you to make sure you follow the rules. My site had a clear mountain stream so it was wonderful to have a water source. I never stayed at the other sites but I know site 8 was the best! Add a vault toilet (with surprisingly nice smelling hand sanitizer!), picnic table and a fire ring...I felt so spoiled! This was the best site I had my whole trip so far and it was close to Grand Teton and Yellowstone. There is a 14 day limit and it is very difficult to get a site (I got there on a Sunday morning and someone had just left). If they are all full, Targhee National Forest offers dispersed camping with no amenities but there are several lakes with nice views. The bugs were a bit of an annoyance but bug spray and campfire smoke helped with that
