Megabus to SF's Legion of Honor and Back

I hopped on the mega bus to San Fransisco today to see Andrew Zorn's exhibit at the Legion Of Honor.  The exhibit was wonderful  and what a great way to see the city. I spent 6 dollars for the mega bus round trip and didn't have to pay for parking and gas. I did have to pay for the metro buses in SF but my Legion of Honor admission was reduced by two dollars for taking public transportation. Not bad.
I spent time in Chinatown and decided that I would return in two weeks to sketch the city. I can't wait.
