A Kickstarter-funded documentary about four guys who ride some mustangs, wild horses which roamed public lands and which they acquired from the BLM, up from the Mexico border up to the Canadian border via public lands over the course of a long summer.
Quite an adventure, with mishaps and drama. Some of the drama felt a little overblown, most of the reason for 4 vs 5 stars. Amazing scenery. Interviews interwoven with the story examine varying perspectives on the issues involved with managing these wild horses.
It is available on Netflix.
