wife and i will have our little guy with us for a long weekend in sonoma. a friend of mine will also join us. he's a wine freak. we enjoy wine but don't have a cellar. we will be there tomorrow, friday, wife, buddy, and our little guy. need a good plan to take it easy, see some great sights, take a few pictures, stay away from tourists, picnic, and maybe hike a little. my buddy will take care of the winery side - but would appreciate any recs ... some great spots to put down a blanket, eat, drink, and be lazy.
