Gee Dave, its been over 3 yrs since I moved east, but I remember the delta club as really active. They actually used thier boats in the winter and had all sorts of activities. Their poor brethern that you controlled were stuck with the usual, but not insurmountable problem of doing things in or around the Sacramento river. We kept boats at Folsom Lake and down near Stockton.
We were members of the Capital City yacht club, and it used to be fun to convince the sacramento boaters to get out of their routine of rafting on the American River and come on down to the delta. In many cases it was a life changing experience that opened their eyes to the unlimited possiblites down in the delta. True, we had an hour car ride from Roseville to Stockton, but once there we had so much more to do. Maybe the cost of fuel has chaned the equation so that staying closer to home is the only monetary possibility. That issue would probably affecting the whole delta boating experience.
