Should be starting in March and going into November. But there are people that drysuit it all year in the Sacramento area. Further north might be closer to your schedule.
I am bringing my Sanger V210 up from Fresno in a few weeks. It will be on the water on a hoist in Disco Bay. Have drysuit will ride. I will be looking for people to sample the glass with during the lonely winter months.... I can ballast anywhere from 700-2000#.
