46,
I stayed on I-90 all the way through the state, but it was night until I got to Billings, where I slept. The town with the "flea market" (it looked like more of a swap meet to me) was just after (east of) Billings, it may have even been the eastern outskirts of town. From there to the border of South Dakota seemed like a wet dream. I'd love it if someone from this site could get their hands on one or two of those trucks, since I don't think I'll be able to take advantage for some time.
