Yeah, RR is absolutely happening, wasn't sure about Lagunitas (not for enjoyment of their beer, which I rather do), Marin was more of a "Hey, it's close by, I've got a wife/baby to keep happy and short car rides might needed at crunch time." kind of thing.
We've got 3 full days, tentatively spread out b/w a Santa Rosa/RR/Sonoma wine country drive on one day, a Muir Woods/Muir Beach/North Bay chillin' day, and a day in the city. The wife, and baby for that matter, are troopers and down to indulge my beerish needs, but I try to pay it back by not dragging to them to every last beer nerd haunt. Thus the need/desire for some closer-to-home spots that can balance out good grub/ambiance and tasty brews.
