Well, the 17, running up the east bay side, isn’t really 17, you know.
I’m from the west side of the bay and spent many years ignoring the east side...17 went to the beach - that’s ALL that mattered! Old Town LG is all that mattered too...great bars, etc.
Trying to tell all the “communities” of the SF Bay Area apart is too difficult to contemplate...typical CA sprawl.
They stop calling it 17 and start calling it 880 somewhere after 280.
