Began Section 3 from Leavenworth, southward on Mountain Home Rd, which was pretty awesome. You cross homesteads perched on the mountain side as well as old mining tracks and encampments. The road is narrow and on the cliffs edge at times so be careful. You do not have to take this road to begin the section 3 bypass. Instead you can take US Highway 97 directly to Blewett Pass if you were short on time.
