Kentucky Bourbon Trail

My son and three Canadian friends are on the Kentucky Bourbon Trail.  Like touring Napa Valley, there is a circuit that can be made with stops.  At one they are signed up for the 1/2 day tour (I forgot which one) which includes trip to see the farms where they get grain, the woods where they chose trees for charcoal and so on, with discussions about what attributes they are looking for in each product.  They were starting out today from Louisville but got hosed by one of the guys caught up in the United Airlines screw up.  The plane Friday night was diverted to Cincinatti, United would not help them at all, said they will fly him to Lousiville in a couple of days, no help with car rental or anything.  So they had to drive up to get him in Cinc. before they can get going on this tour.  Oh well they have a few days.
