Walt, I did not even know that you were at the show. The one thing that drove me nuts was they don't give you a layout map that shows where the exhibitors are located in the convention center. There is a map at the entrance table where you buy tickets, but it is a pain to run back there just to check where a particular person is sitting. They really should hand out a layout map that you can carry with you, much like would happen at a car show.
Another tip - the line up to buy tickets was quite long on Saturday morning. However, I bypassed the line by going to the Chicago Pipe Club table and buying a membership to that club, which allows you to walk right in and avoid the line. It costs $5 more for a membership than it does for an admission ticket, but it was $5 well spent to avoid a long line.
