Going to utilize sections from many of ACA's routes.
Basically TA from Florence to West Yellowstone. L&C from Billings to Williston. NT to Osceola. NL to Wolf Point. LEC to Buffalo area. NT to Conway area. AC to Boston.
There is a section that I'd like to travel, but ACA does not have routing ... Yellowstone going nw to Billings. Looks like way to go is:
>> out of Yellowstone's NE gate using US212 to Cooke City
>> continuing over Beartooth Pass & into Red Lodge using US212
It's at this point I am uncertain. Options appear to be:
>>>> continue on US212 nw to Laurel/Billings
>>>> take State308 out of Red Lodge to cutover to State72 & then US310 north to Laurel/Billings.
There's not significant distance difference ... 200 vs 210.
US212 route seems to have just 2 "towns" between Red Lodge and Laurel/Billings, while State72/US310 has 4.
Have no knowledge re relative merits of these roads between Red Lodge & Laurel/Billings for cycling.
Any info you can share will be big assist.
