Just gorgeous!!  A real treat  of a walk!  I did this on my own and was just entertained beyond belief!!  It's a bit touristy, as I was, so I get it.. I live in a touristy part of SF, so I try to turn a blind eye and a deaf ear.  I wish I would have bought some Cashmere or a tartan skirt!  2 real regrets! The pics I took were fabulous.. great photo ops!!  I wish I would have gotten on a tour, though.
