Hey Guy,
It was nice to meet you and it's good to see that you guys made it out to china wall.

Last time I went to glamis I was looking and looking for china wall but couldn't find it. My fiancée at the time is a new rider so we were just riding on the outskirts so we didn't really go deep in to the dunes.

You can also get to China wall if you ride along the wash road to wash 22 then make a right and head out through the wooded wash kind of cross it diagonal and then you can ride in to the valley that China wall's in from the north side and you only have to cross 5 or 6 medium sized dunes. 

P.S. this is how you get back to the washes if your broke down or you want the easy way out.
