I see you are in AZ.. Are you in Yuma? I lived there twice...once from 76-77 when I was the PX Officer at MCAS and then again from 1980 to 1987.
We are in Tucson, about three hours from Yuma. We go through there a few times each year. I love those sand dunes. Prior to moving here, I was stationed in Death Valley for five years with the Park Service. Going up to Ridgecrest/China Lake next month for a friend's retirement party from the Navy... haven't been there in so long.
