Avoid the Esplanade on the weekends. As for the roads, they're all in terrible condition... so prepare yourself for a headache if you miss standing up for just one of the potholes. Financial District on the weekends is dead in terms of traffic - like a ghost town.. can be fun if you don't want to mess with much traffic. The drivers are bad, but predictably bad ... god I can't believe I'm still here. Oh well, much worse places to be...
