So, here’s a bit of a trick to get longer at a meter: pay with coins, but take note of the meter number. When the meter’s about to expire, call up and you can get additional time—up to the limit of that particular spot, often 1 or 2 hours. The fee for using pay-by-phone is $0.35 I think, which is totally worth it for being able to park twice as long in the same place without having to head back to your car.
