Hi Hunnybunnie,
I live in San Francisco as well

and I also notice how mean the muni bus drivers in this city are. Several times I see someone running, being almost at the bus, and the bus driver just shutting the door right in front of their nose!!!! Gets me sooo mad!!!
I take the Muni every day to work so in my free time I haven't even attempted taking Simba on the bus.
Hey, if you don't have any plans this Sunday you should come to the Yorkie meet-up at Allyne Park in the Marina district. It starts at 1 p.m.
