I only stayed for a little over an hour. I did meet Bob, and saw a few friends. I'm not really interested in Menards' trains because they aren't scale. I never expected to buy anything there so I wasn't disappointed. I didn't spend a nickel. I spent more time driving back and forth than I did inside the show.
Large Lionel and MTH dealers: Not sure, it was an all scale show. Vendors were mostly from within a 100 mile radius. No manufacturers except Menards.
Don't know about the food, I didn't have any. I suspect it was pretty standard.
Personally, I only reminded myself why I stopped attending shows years ago.
