I was in traffic downtown Tampa and my lane was stopped, the other two lanes were flowing nicely all of a sudden a lawn truck towing a trailer goes over these rail road tracks and the whole trailer bounces off. It passes the truck crosses the median and through three more lanes of traffic on the other side with cars swerving all over the place. It came to a stop in an empty parking lot and not a single car or person was harmed. I was like whoa that guy was lucky nothing happened. I'll bet he double checks the chains next time, and makes sure the trailer is latched.
