My grandparents lived in Sonoma after they moved from Novato and Petaluma in the 70s/80s. I know that area somewhat. There are lots of nice places out that way, and for some reason, suddenly Guernville comes to mind.
Can you tell me what rig you are shooting with and what you are doing for post processing? It looks like the saturation has been turned up, almost like shooting an old Nikon D1 raw. I really ought to be posting more of my own pics to share here with you and Swampsniper too. Which photo storage site are you using?
