I love camping. I went to camp as a kid, not the nice camps with air conditioning and a pool, the kind with ancient cabins that are barely closed to the elements. The camp was on a lake that was not the best for swimming in, but it was the only option. My family also would go to a campground every year for the week of the Fourth of July. The same families had been renting at this campground for years and usually the place was booked years in advance by the same families. Yes, it was a first come, first serve basis, but no one wanted to book the place up to three years in advance.
Therefore, it was the same families, and generations of families, that were there that week, every year, since sometime in the 60s. Every now and then, new families would come, and others would stop coming, but everyone knew everyone. Obviously, because we were not all related, it was fun to have crushes on the other kids when we were young, someone we only really saw once a year. Nothing much really ever came of that, nothing lasting at least.
