I remember when 880 was the Nimitz Freeway aka Hwy 17. Now it's only 17 after you pass 280 going south.
I remember when Calaveras Blvd. was actually a Blvd. and not a freeway.
I worked at NASA/Ames when Boeing had an office there. Civilians were not allowed to buy cheap smokes from the little store on base, but we could buy anything else!
I remember Frontier Village. In fact I just joined a facebook group dedicated to remembering FV.

I loved panning for gold!
I remember when it was Marriott's Great America and not Paramount's. I also remember the day they closed that one coaster that was 8 loops high and redesigned it to only three loops high because someone died when they decided to jump out of it.
I remember when you didn't have to pay for parking around the Santa Cruz Beach Boardwalk. :p
I remember when it was just farmland all along 880 from 101 north to around Auto Mall Pkwy (oh, I mean Durham!)
I remember when Fry's Electronics used to be Fry's Foodstores. :p
I'm sure that there's more I remember...but it's further north, like when there wasn't a Foster City, it was part of the bay! I remember the old Dumbarton Bridge, as well as the old San Mateo-Hayward Bridge, both have been changed.
I remember what West Oakland looked like when the Cypress Structure was still there...thanks Loma Prieta!
