Deadwood SD to Cody WY

I will also have to say Hwy 16. We are planning a trip to Colorado and Wyoming next year. We will be leaving Yellowstone's East entrance and heading to Hermosa, SD. I asked about the best route in the Roads and Routes area of this forum. I was told "Hwy 16" so that's what we have planned.

Have a great trip. I wish I was headed there now.
