We all have memories of things we did as kids to cool off.
When Grandma J was a kid we had a little pond that all the neighborhood kids would splash around in. This was without parental supervision. Some of us couldn't swim! We all survived.
There wasn't such a thing as bottled water. When frolicking in the summer sun got us all hot and thirsty, it was the rubber garden hose that quenched our thirst.
One thing Grandma J did was still popular when her own kids were young.
This activity isn't recommended for adults. Grandma J knows what she's talking about....she told you all about Rita's incident three years ago. It's a perfect example of why sprinklers aren't for sissy adults.
