My last 2 high schools (of 3) were in really rural towns, so there was no opportunity to go off-campus for food. There wasn't a fast food place in the town. The town was so rural that some people drove tractors to the prom. We joked that a drive-by shooting went "clip clop clip clop bang bang."

I don't recall any rules for driving. The student parking lot was first-come first-serve.
The drinking fountains always remind me of the 2nd high school. I stopped drinking from them because most of them had chewing tobacco in it. Blech.
