Places to fly mid week after Oshkosh?

I am driving the RV with glider in tow to Oshkosh next week, after, I am driving to upstate NY, are there any gliderports/clubs along the route that offer guest tows to visiting pilots? Maybe rv camping close, Say in the eastern Wisconsin, lower Michigan, northern Illinois, northern Ohio western NY northern PA areas? I won't be staying in one place too long a day/tow or two at most. Just want to see and meet other places/pilots maybe some xc

Being generally a western pilot I have little knowledge of places to fly on the weekdays in the east! Thanks for your responses!
