I may put my buddy Keyton on to this. He's a journalist, get him to interview a few of the local business owners. I'm pretty sure most of them love the increased traffic and business that comes along with this meet. See if he can get it in the local Addison paper, hell at the least contact the city and discuss this with them. The location is great for that meet. It shouldn't need to be changed due to the tight ass police and the empty gym. The gym closes at around 8pm, even though it's a 24/7 gym.
If Winfield had more room and businesses downtown I'd talk to the city about having it here. They close one of the streets every Monday for a classic car night. They'd love the business and increased traffic, but their aren't enough food establishments to cover all those people let alone the parking space. I know a great spot right off of I88 and I355 we could possibly recommend, there are plenty of places to eat though the only a few that you can walk to. Right next to where I work, is a huge parking lot off of Butterfield Rd. in Downers Grove. Olive Garden and North Beach are there. I think North Beach might be the only one that might complain, but I'd half expect they'd get some good business from a meet this large. If anyone has the contact info for the organizers of Friday Night Lights PM me and I'll pass along the info and see whats what. The parking lot is much much larger, and you can also walk to Hooters!
