A classic from Reed Merschat back in about 2001, this video caused a lot of hate back in the day because it showed trials bikes riding in skate parks. Gasp! Haters will continue to hate though as a lot of the "hardcore trials community" (read: nerds) will bag on Danny Mac today for not putting all his effort into going a few inches higher on the ups and growing a more flamboyant French unibrow.
This video has a lot of riders in it that are still highly influential over a decade later. Jeff Lenosky, Ryan Leech, Chris Akrigg, Marty Ashton, Lance Trappe, and many more show you the confluence of street and trials riding in this half hour of class.
