Did you go to summer camp as a kid?
I was poor and my family couldn't afford to send me to camp, I went to a church camp when I 10 and 11. I started working the summers when I was 12.
My kids go to some sort of camp most summers. Until this year they were day camps. My oldest 2 are going to overnight camps for the first time this year and it's not cheap.
My middle kid just got back from his and he had a BLAST. He went to

There is also Camp Fern in east Texas, it's where a lot of well-to-do people in the NWLA send their kids to camp.
Summer camp is still a thing, for those with means.
