There is a small group of boaters located in the Fairfield area, about 35 min from Sanoma. Most of us are affiliated with the Air Force, either Active Duty, or work for the Air Force. Though we only have 2 or 3 class IV-V boaters we try to get out as much as we can, usually going up to the South Fork of the American (all that is running right now). I am a comfortable class IV-IV+ boater who has done some class V back east and looking for some one to try to get on some bigger creeks with.
If you have a facebook we have a group, Kayak Mafia. Check us out.
