The video does not do it justice because I was standing and it's really hard to tell that the bike was on a major roller coaster. These were every bit of 2.25 foot deep, very close togeather and went on for miles. They were made of fine very dry sugar sand and were pretty difficult and very tiring to navigate without falling over. I decided to take this long arduous route to build sand riding skills and my knees. The video makes it look like child's play though... not. This is on the 701. Even though it looks simple enough I'm putting it up so when I take people there they go Oh.... Yea... this ain't so simple.
