I was lost one Sunday, going to get some yard signs for a political issue. I drove by a public school that had a lot of cars in the parking lot and thought they might know what was what, so I stopped the car and walked up to the buillding. The door was locked, but there were people inside, so I knocked. I saw shoes on the floor, and, then, saris. Turns out it was a Hindu service going on. Some guy came to the door, cracked it, and told me so.
This was at a public school.
So?
There are a lot of public schools here locally who rent space to churches on weekends. If they have to stop doing that, I look for them to come crying that they need a tax increase to support the schools.
