Wind at the Sand Dunes

My brother and his girlfriend came to the Valley for a visit and decided they wanted to go to the dunes . As it has been raining almost everyday, I thought well, we'll see how bad they really want to go. The day scheduled for the dunes visit was Friday and not your typical dunes weather but they wanted to go anyway. I decided to not climb the Sand Dunes so I painted. I and the mosquitos took refuge from the wind in some trees and this is what I painted... I was lucky I finished this before the rains came.
