re: Any of y’all ever been to Yosemite ?

For your trip SFO will have the best choice of flights, but do check San Jose, its served by United and is much closer to Monterrey.

Main attraction in Cannery Row is the aquarium which is a hit for every age. A deep-sea exhibit recently opened.

In San Francisco do not park a rental car on the street even for short periods and seemingly nice places like Golden Gate Park. Window smashers prey on rentals.
