Yeah.. Put a little baby circle track right smack dab in the middle of redneck NASCAR country and try to guess how that's gonna turn out... Rubbin's racin'!
The absolute DUMBEST thing about them whoop-dee-dos is where they put em... On the TRUCK BYPASS running around the edge of town! You gotta be an idjit... Ain't no other dang way. 
All the ones locally have the centers built up so you can't just drive over 'em--some to the point it would take serious shelling to dislodge a crew served weapon up there.
I still haven't figured out how they are going to plow the snow out of them....
But on dry roads, if you drive like an Italian, they're okay. It's all timing, and budding NASCAR types can handle that.
