LDP
LDP stands for Long Distance (Skateboard) Pumping, also known as "Skumping."   Longboard-skateboard technology has rapidly advanced since the 1970's, and along with those changes is a new breed of distance-pumping skateboarder.  

LDP sessions can be casual 5- to 10- mile pump cruises on flat bike / rollerblading trails, or a 26-mile all-out marathon, where a gyrating, pumping motion is the primary means for moving the skateboard forward!

We usually go for a few LDP sessions each week, come check it out!
