She starts at Medina right at the Old Timer convenience store. All three sisters are camera shy, so you won’t be seeing a lot of photos of them. Stopping on the side of the road to take panorama photos is dangerous because there is little to no shoulder, so these photos will be brief. They were taken at safe stops (don’t worry the photos get much better on the Mexico portion of the adventure).
The below photo is where 337 starts out. Note the radius and the Falling Rock sign. This is actually one of the milder curves.
The Falling Rock sign is a warning because the sisters cut through rock hills. Here is an example of a canyon that was cut for this road.
The above are some of the few places where I had shoulders to pull over and take photos. That’s my windshield in the lower part of the photos.
