I will be living in San Francisco for seven months from the beginning of February to the beginning of September, and I'm looking for places to take affordable (and accessible art, language and other classes). [more inside]
I don't know much about architecture, except that I really enjoying time looking at good examples of it - and will go see places just for that. Where can I find free or low cost classes to learn more about architecture? (Second choice would be a good online resources). I'm not only looking for classes (which I can do via google), but people's experiences with them I am in DC. Transit accessibility is more or less a necessity.
