Did sections 3-5 of the Montana BDR (Butte to ST Regis) over the course of 4 days last week.

Day 1: Butte to Moose Creek campground which is about 20 minutes SW of Helena.
Day 2: Moose Creek to Lincoln. Stayed in a Hotel, ate at the Montanan Steakhouse (amazing), and toured Sculpture in the Wild.
Day 3: Lincoln to Seeley Lake. Short day of ~70 miles. Stayed in a cabin right on Seeley Lake. Ate good BBQ and had the minor RZR issue addressed at the Polaris dealer there. Their customer service was amazing!
Day 4: Seeley Lake to ST Regis. Long day of about ~130 miles. Rain had knocked down the dust and smoke so we could see the sights better.

All in all it was a beautiful trip that I'd reccomend to anyone.

Looks like a good time and a beautiful area to ride.
