Are any of yall totally blind and without a dog?  Not sure what to do but my wife likes to go to concerts and it gets rather expensive to take someone along.  What do yall do when you have to go to the rest room as a blind person?  Do you ask someone for help?  DO you go in and hope to not hit some one?  I've had a run in when trying to go.  I accidentally bumped into some one and they about came unglued.  Email off list if this is way far out.  I just figured with the talk of the ham show this problem may be faced by some one.
