This stretch of road just northwest of Port Jervis is known as Hawk's Nest. The road is about halfway up the cliff. If it looks familiar that's probably because numerous car commercials have been filmed there. It is really fun to drive. The fabulous Commonwealth of Pennsylvania is to the left of the icy Delaware River in the top picture. The road gets crowded on summer weekends, but it was empty on a winter Tuesday.
Unrelated: I wish I had known about this in advance. Today was National Pie Day. Come on, American Pie Council, you need to get the word out sooner!
