Davis street piano hours?
Is that an official rule, or did some random person make the sign? There are no hours listed here, even though other listings do have time restrictions.
Having some limit does make sense, since people live above Tedeschi's, etc. But 9 pm is ridiculous. I think a more reasonable end time for such a busy location would be 11 pm or midnight. What does the city noise ordinance say about street musicians and other noise at night?
