It’s all over downtown. You pick a parking spot, remember what the number on the pavement is, go to the meter within 20 feet or so, and follow the instructions. You pretty much punch in your parking number, then drop whatever round coins you have, and it will tell you how many minutes you paid for. And it gives you a receipt with your “done” time printed as a reminder.
Much like home! Except that, if you shop too long, you can go to ANY meter, and add more money to your very own spot without walking back. And it’s very affordable.
