Yes - we just stayed at a GREAT place on the Russian River just north
of Tomales Bay. It was a wonderful campground with lots of riverfront
and even a nice sandy beach. Cassini Ranch Family Campground in
Duncans Mills, California. Phone is 707-865-2255. Very well stocked
campstore and they'll even blow up your air matress for a modest fee.
Nice little town with restaraunts etc just down the road. They try
to warn you away from the riverfront campsights because they have no
shade but we loved them. I seem to remember that 5B was both
riverfront and had a bit of shade.
