I somehow overlooked the Maah Daah Hey as being a possibility in my trip out to Montana next week.
It's inspired me to juggle my plans on getting out to montana a bit. Overnight train to williston wednesday night. An afternoon ride from Williston to CCC campground on thursday. And, likely - a very humbling ride from CCC campground to Medora on Friday. Here's to hoping it doesn't rain - because, I Have to be in Medora by 8am Saturday. If it does, it's gonna be one huge tease - as I ride the entire length of the trail by highway instead of single track.
Either way, Amtrak tickets purchased. Thanks for the reminder!

(also, sweet video!)
