Sour Afternoons |A Skateboarding Short Film from Brian Bitterfeld on Vimeo. During this past winter's Research Tour, we had the pleasure of hitting Aspen as our final destination. We met some good people there that took us in and showed the YRC crew some proper hospitality. We've kept in touch since then and hyped that they are supportive of our vision. Here's a quick short of the homies getting after it at their local skatepark, Rio Grande. Riders: Aaron Hooper @filmforfood, Ryan Brown @hand_pressed, and Nick Becker @mystiksnyx. Film/Cinematography: Brian Bitterfeld @bitter_pictures.
