I was thinking of this either on the way down or the way back. If I do this on the way down I'd probably blast up the superslab most of the way back. It's not really northwest. I could push it over to the west a bit to hook up with people. I could do Boise as well, BTDT.

East Helena-Afton-GrandJunction

Not sure about that last leg. I can do over 500 on the slab (638 is my record) but with two-lane backroads I try not to plan for more than 350-400/day. Takes longer, but that's kinda the point, right?
