truck horn

so one of the guys at work was leaving for lunch, and he asked if we wanted to hear his train horn. being a little confused, i said yes. so we walk outside and he gets in his truck and hits the horn. and it is a genuine train horn. he bought it from amtrak for $400, when it normally sells for $1,000. but it was crazy; an actual train horn on his truck. all i could think about was the damage he could cause in traffic (or on the road in general) if someone made him mad and he used it.
