Exit 193. Go west on Bridgewater Rd next to (north of) the interstate. Hoover Rd., County Rd 91 is the gravel road on the Rt.
In 2019 someone posted a youtube video of the Darke Co (Ohio) Fair with Primetime Amusements and a Sky Wheel with on ride footage. I don't know anything about Primetime, was looking forward to the first time they would play the Cuyahoga Co Fair in 2020 (canceled by the china virus), and their website is now dark. Was that their Sky Wheel or someone elses?
Could not tell if the one at exit 193 is complete, other trailers in the way, but it looked it.
I did see something that looked like an old Chance Rock'N Roll ride, but I'm not sure, I haven't seen one of those in over 30 years. And last I heard the only one still running is at Knobles Park in PA. Does anyone have a portable one still around?
