The wall also adds some physical protection from the wind. Also creates a more quiet, restful, and intimate atmosphere. Just my two cents, I was naked anyway. But I found it really restful, where I didn't have that feeling at other places.

My wife and I (virgin burners) really enjoyed your bar! Got leid and visited several times. Favorite spot on the playa. Your bartenders were incredible and so respectful. Very nice. We want to hang with you next year!
