My dad loved to water ski, and wanted to be in clear water in the Ouachita Mountains of Arkansas, rather than the red dirt water near home.
We started when I was 12 - five kids sleeping in the open bed of the pickup, mom and dad in the cab.
The next year, he got a shell to cover the back, welded legs to a steel set of springs and he and mom had a bed. We got borrowed chaise type lawn chairs. An old sheet to cover us and keep the mosquito's off, a sheet of plastic if it rained.
When I was 17, we got a tent. Dad's idea of camping was the same spot in the same campground on the same lake 20+ weekends a year.
I was off in the Navy when he got a popup, which lasted two years before he got a Shasta 21 footer (my brother uses that as a lake/ fishing place now - 35 years later).
Started my kids camping when we were in Japan in the early 80s.
Met my DW in 1995, and we tent camped, including introducing the grandkids to tents at Albert Pike in the Ouachita's before they were school age.
After having the tent blow down, and having to drive two miles to the bathroom at Palo Duro Canyon SP, I told her we were getting a trailer. We love it and haven't looked back.
