Mile...Mile and a Half.
This is an amazing documentary. It's just the story of a group of people who got together and wanted to film the John Muir trail in CA. Holy hell, it gave me and DH spring fever so bad we planned a 3 day float, a 2 day bike ride, and a 3 day backpacking trip for April, May, and June over this break. It is breathtakingly beautiful. It also has the kind of whimsical funny trail moments you get. Highly recommend for anyone who likes outdoor scenery and nature stuffs.
ETA: It's a 4 week hike over 220+ miles.
