We were driving back to our motel after the day's shopping excesses, and we happened to pass an elementary school.
There was one glaringly obvious thing that underscored the tremendous differences between Grand Forks, ND and Las Vegas, NV.
There was NO FENCE OR WALL around the elementary school grounds. Just lots of lovely green grass. I repeat, because I still can barely believe it: NO FENCE around the elementary school.
Anybody and his uncle could walk right up to the school building. The kids could wander right off the campus and across the street.
