Runaway Float Trailer

In a scene somewhat reminiscent of a recent train disaster, Curly forgot to set the brakes when he disconnected the trailer.

Giant trailer at bottom of street.  

This started to roll down our hill, with Curly trying to hold it back and smoke coming from his running shoes.  Larry got the Bobcat running and chased after it.  It rolled onto a busy street at the bottom, and no big smash!  Were they lucky or what?  I am way too slow to whip the phone out for a video.
