On the first leg of Hwy 120 there is a stretch of road about 6 miles long where you wind your way up a canyon. There is two roads that wind up this canyon, one on the left side and one on the right side. It's always been strange to me because the Hwy is on the left side but the road on the right looks to be shorter.

Here you can see both roads.We came up the road on your right.
