I don't. Being ignored in the pro shop, getting insulting answers when I did get attention, unclear signage...
Can't say I've been to a lot of tracks, but I do know I wasn't well treated on my three visits there. ( I visited one in Cincinnati, used one in Vernon hills, visited Harbor three times, and of last weekend Oshkosh)
I hope there is a track that opens to take it's place , and they do better.
To draw a comparison to the paintball field across the road, CPX didn't steal customers, they drew more. They drove the demand that lead to several new fields opening.
I can only hope, that's what windy city will do. :-)
