Sorry to hear but Bob falls an awful lot.  Many of you probably don't remember when he fell at Mohawk I believe in the early 90's?  Was so hammered I think he fell down the escalator and broke both arms.
I think early 2000's he fell again and broke a wrist?  Can't remember all the details but this isn't anything new.  Great trainer and very very sharp conditioning an animal.  Just has a bit of a drinking problem.
