The swimmobiles that cooled off a hot city These were the “swimmobiles,” pools attached to a truck which could be parked on a street all day and conveniently towed away at night.
And if there weren't swimmobiles, at least the firemen would open a hydrant and all the kids would run around in the spray.
I'm glad I grew up on a farm. (I don't know why my minds works this way, but my first thought was "I wonder what the ratio of urine to H2O is in that thing?"
