I will stop until 16 and then I'll go to Avalanche for the night as you said. Perfect! Meanwhile, my planning brought me in the east side of Montana. I saw to go to Dickinson from Glendive there are some roads out the interstate 94. But I'll will travel with a road bike with thin tyres and I don't know if will be a good idea to cycling on unsealed roads. Is so dangerous to do a short piece of interstate 94? How is the traffic there?
Thank you for every suggestion!
p.s. I have received the Northern Tier maps, section 1 and 2. Full of informations!
p.p.s. Regarding Amtrak.. I bought a ticket from Portland to Mt. Vernon, I did a reservation for the bicycle. Should I specify that the bicycle is not in a box? Is not so clear on the Amtrak site. I saw there are many options to carry the bike onboard (full size bicycle or folding bicycle) but when I reserved my travel I have only chose 1 bicycle...
