There is a railroad overpass in KCMo like that. Has warning signs on all areas of the bridge telling of the height limit. But, one driver thought he was okay and slowed down to go under. Needless to say he got stuck. Couldn't back up or go forward. Then a young scholl told him he could solve his problem. The driver said okay do what ever you think it will take. The young lad proceded to let half the air out of all the tires. The thanked him and drove on to the nearest station to pump the tires back up.
