I'd second that....weekends are the time to ride the GG Bridge since you have the best view...looking toward the ocean and no tourists (on foot) to worry about....However, with that being said you can run into two types of worrisome cyclists.....very slow, clueless bike riding tourists or, very fast dudes who think they are the only ones on the bridge.....at least they installed guard rails so that if you do wipe out, you won't likely get run over by a car......
