Sounds like you've got a lot of time to decide whether you want to camp by yourself (a slightly misleading term, as one usually has neighbors) or with an "arranged group". I (genuinely) don't know why, but that phrase makes me grin.
A lot of people enjoy the freedom, the reduced chance of interpersonal conflict, and the challenge of having a camp of one--or a very small group. (I can tell from your use of the term "radical self-reliance" that you have indeed done some reading already!) Others like the amenities, responsibilities, and prestige of a theme camp. There are also village-style camps, like Orphan Camp and Stag Camp, that are very social but with few amenities. Anyway, lots of choices. If you decide to join a camp, emailing interesting ones in mid-Spring or earlier is best, as many camps close their doors in May or June.
