hi Keith, went to Ada again over Christmas, did not have your phone number, the plant south of Tinker was the GM Plant, the Ford plant was/is on Classen and 1st street, my dad said that a company out of Memphis is buying up the Ford plants and converting them into condos/hotels., my dad owns a bunch of buildings in downtown OKC. Sorry I missed you on my trip to Ada. Left OKC Saturday morning and it was very icy in OKC on I35 from OKC to Stillwater, many wrecks, but made it back to Denver with not issues!
