OK I see, parking lot NEXT TO the stadium. I still say should be no problem as the football game is not taking place on the lot. So the visitors walk across it to the stadium....just like my kids walk across the sidewalk and lot when I drop them off at school. I don't view that as a school sponsored activity taking place ON the school grounds, any more than the football game is taking place ON the parking lot. Yes the school does OWN the lot.
Some have argued that a school event (other than sporting event) taking place on non-school property is NOT off limits because the school doesn't have the right to control the property. So even if the Band were marching down I-35, I'd still argue not off limits .
