lots of good stuff. there is a cool DIY in petaluma, there used to be one in Santa Rosa, but it got destroyed, but I heard rumblings of a new one. Sebastopol has a pretty cool park which is a little west of Santa Rosa. The Santa rosa park is a crazy beast thats a snake run/lumps/hard to skate, but very enjoyable. If you go a little farther from the area is St Helena thats fucking massive and all sorts of rad.
are you staying in the area or what? Lots of really, really cool street spots out there too.
