It's not as twisty as it looks. The highlighted wiggles at the south end are all through towns, and while I wouldn't call it boring on the way to Ford City it's certainly more sweepers and lazy sweepers than anything twisty.
Good for the cruiser/tourer crowd, and if you're some hot-blood sport biker you'll want to crank things up a bit, but it's not particularly safe to do so on a road with this much traffic and the police presence.
All in all. 'Meh' it's okay.
