Planning on using transit this weekend? You may want to take a look at Golden Gate Transit's Detours page, because there is a ludicrous amount of stuff happening around Marin for the next couple of days. In short, routes 10, 19, 22, 70, 80, 101 will be effected at some point on May 18 and 19. Most of this will have tight parking or be in places where your car will turn into an oven, so transit will be the best way to get around, as long as you know where to go. And it might be a good idea to make Route 19 (or perhaps the ferry) your designated driver after the Tiburon Wine Festival. Here's what's up:
