I see middle-school kids biking home from school in my suburb and when approaching the intersection (not a very busy one, mind you), they all dismount their bikes and walk across the street. I know that's what you're supposed to do, but c'mon, they're kids.. When I was that age my friends and I would race across the street without helmets flipping the bird to the crossing guard, so it's a bit unsettling to see them all obediently get off their bikes and single-file across the street, even when there are no crossing guards in sight.
