Wing Ding has been here in my city twice in the past few years and it's a big deal. Every hotel in town was booked full as well as in some outlying areas. I went to the first one, the venue is only a mile from my house. You cannot get into the vendors area unless you are a GWRRA member(at least that's the way it was then). If I remember correctly, there were between 9,000 to 12,000 Dingers here depending on what report you read. It's been in Madison before too.
