No offense to the people who live there (including my own family), but I think both of those towns are boooooring. They're great if you have a family, and want the full suburban experience... larger homes with yards, less noise, "big-box" stores, etc. But for a young-ish, single person like myself, I'll take the city over them ANY day. Some other places that are "city-like" would be Berkeley, Oakland, Daly City, and places right next to those towns. But really it depends on what
you want, so I'm not going to say Walnut Creek & Sunnyvale aren't the right choice. Sorry to be so wishy-washy!
P.S. I do remember you, but can't remember the whole conversation & what you're looking for.
