Climbing large sand dunes can be a lot of fun. Running down them is even more fun. It was a lot of effort to get to the top this 600+ foot dune, but definitely worth it. You can find the Kelso Dunes in Southern California in the Mojave National Preserve.
For fun I added some background music, also to cover up my panting because I was really out of breath. Stay to the end to watch Josh go all the way down the dune. rk
