We made great time coming up to Columbia.  Very little traffic around D.C. so we sailed along fairly well.  We arrived in Columbia, took the exit but drove past the hotel.  We found ourselves in the middle of a residential neighborhood in a 65 foot semi with no place to turn around.  We came up on a school and figure the buses have to go there, there should be enough room.  I made the turn around and came back to the intersection.  I made that right turn and then we heard it – a loud “boom” as my trailer tire drug across a drainage ditch and ripped everything to pieces – rim and tire!  We arrived around 3:45pm but I had to start finding someone to fix this thing – on a Friday!  Fortunately, we did find a company and a few hundreds dollars and several hours later, I’m in the hotel room.  This better be a good show tomorrow night!!
