Well, I've never heard it called a "touge", mostly because the guys who used to run it regularly were sports car guys and hot hatch enthusiasts back the 80's (Golf GTi's, Corolla GT-S's, the occasional Cosworth Vega or Chevette Scooter, my dad's Omni GLH), but Nickel Plate Diagonal is a nice twisty bit of tarmac out here in Ohio.
The guys mostly just ran against their stopwatches since it's only a two lane road, but's like someone grabbed a section of the old Nordschleiffe Nurburgring and planted it right in the middle of rural Ohio. Plenty of elevation changes, some great fourth and fifth gear sweepers and lots of second gear tight stuff.
It's a lot of fun.
There was also Old Ford Road. That was fun because it was a really narrow two lane (no shoulder) road that dropped down sharply into a set of 90 degree corners. The really fun part was that you only had a mile and a half of road to really race on until you got to this one lane steel deck bridge. So the race was whoever got to the bridge first. My dad rolled his first GLH racing on Old Ford Road up against my grandpa's Celica Supra. My mom and my grandma had a lot to say about that one.
