I did with a few friends.
It was cool. I tried a 7X7 inch travel Kona Stinky. Rode up the Truck Trail and down the Luge. This was my first time riding a big bike and it didn't actually climb that bad. Usually I ride a XC FS Kona or an Enduro. But definitely the thumbs up to the Fox DHX coil shock on that thing. Made the bike pedal pretty well but was uber-plush going down the luge.
The Path guys and Kona guys were cool guys.
