Eastern Big Sky Byway (Rt. 200S & 13)

After leaving Medora, S.D.  we needed to get up to Rt 2 so we got off the interstate and headed north.  Rt. 13 is a good two lane but the road methodically rises and falls several hundred feet every three miles for about 60 miles. Beautiful country, lots of Montana sky, and lots of wheat ( but very little traffic).
