BillPa1 here. I live in La Mesa, CA and Anza Borrego is fantastic from about February on. I camp at Split Mountain and drive about an hour off the pavment to very promative camping. You are mostly alone and there as some fantastic sandstone structurs to see. I just took delivery of my SMB in Dec so my first shake down cruz will be in a few weeks. I am waiting on my solar cells and rack from Alumaness.
Just got back from a weekend in the Fish Camp area, had an awesome trip, camped with no one else around, did a couple of sweet hikes to the Wind Caves, and The Slot, great spot. Started to Diablo Drop, but stopped mid way through Broken Driveshaft Gulch, when I thought it was gonna get too gnarly. Good stuff otherwise though.
