Made a(mother) mistake - now in N Dakota

What is this plant? There was a whole field of this plant right beside the Hwy.

Decided to use the N to NE wind rather than fight it all day - so I went S from Brandon on the shines looking on the map Hwy 10. I planned to ride about 30km S and turn E on Hwy 2 but Hwy 2 had gravel shoulders - ouch. So I continued S on Hwy 10 which immediately went to gravel shoulders too!! See one of my photos. I continued S about 90km and crossed into USA. Which provided paved shoulders from there on. Finished going E on Hwy 5 and will plan to stay E on it for about 2 days. Saw a young coyote today along the Hwy and my usual quota of Garter snake and other hwy carnage. In Belcourt ND staying in the casino Hotel. I've never heard of this place before either!!!
