Just wanted to add two data points during the road trip. In South Dakota, food and gas options on 90 were few and far between. We ended up stopping in Murdo, where we ordered a couple of hand formed burgers at Murdo's Drive-in. In the land of beef, these were simple but expertly prepared and hit the spot and provided nice variety to the common chains you see on the highway. The staff was very friendly.

On our last day, we drove through Missoula, where we ordered a pizza to go from Mackenzie River Pizza Company. Browsing through the menu on our phones, we opted for the Branding Iron - Italian sausage, jalapeno peppers, mozzarella and crushed red chilies. It was interesting to see the Italian sausage sliced rather than the crumbles I am used to seeing in Chicago. We weren't too impressed with Italian sausage as it lacked flavor. I couldn't really detect the sourdough flavor in the thin, crispy crust. Being spoiled with all the great pizza options in Chicago, this pizza didn't impress.

While we waited, we made a quick detour to Big Sky Brewery for my husband. He picked up a 6 pack of Scape Goat, which he recently had in Chicago. (maybe Haymarket? I can't remember)
