We kids taught ourselves.
There was a life guard.
It was just a country lake
We paid a couple bucks to get in from money we had earned, swim, watch the girls, fish and maybe get a dreamsickle.
We’d ride our bikes 4 mi out there along a heavy truck route with no adult supervision.
Ahh to be a kid again.
I think I feigned drowning once at about age 12 when some cute gal was life guarding.
She sussed me out LOL
It was worth a clumsy try LOL
