So THAT’S what made my eyes burn so bad in the school pool at Tatum, New Mexico back in 1960! the school blamed chlorine. Believe it or not, back then New Mexico had great schools!
Carlsbad schools, at that time, simply sent everyone to the Pecos River to swim.
“...sent everyone to the Pecos River to swim.”
THAT was better...just natural fish and animal urine 24/7/365 ;)
