California here I come!

I'm off to California tomorrow with my husband and mother in law for a hiking trip for her 60th birthday. Hopefully just because it's her birthday trip won't mean that she wants to dictate everything that we do because there is a bit of shopping I'd like to do and of course I need to hang off the outside of the trollly in San Fran and sing this song. I know it's about St. Louis but it's the only trolly song I know!
