We went out this AM w/the intention of doing the 'freeway ride' from eastern Contra Costa to the Carquinez Straits, but the wind out near Bay Pt BART and the trail parallel to Hwy 4 about knocked us over. Upon further review (and much debate), we turned back and did some of the usual stuff out in Antioch and Oakley. We were all happier for the experience and will do the aforementioned freeway ride another day.
