Arnold,
Some of my all time favorite cruises are up a couple rivers and sloughs that flw into Suisun and San Pablo bays....three in particular. Suisun slough all the way up to Suisun City...good Marina and docking in the middle of town. Secondly, up the Petaluma River all the way to Peteluma with the marina in the middle of town....this is the city where the all time great movie "American Grafitti" was filmed. And third, maybe my favorite, up the Napa River to the town of Napa. Used to be able to tie off in downtown Napa but those docks were closed and you have tie up in the Napa Marina about a mile out of town. Great trip though. Let us know where you end up
