There's a 3 hour parking on the eastern side of Marion Ave (
http://maps.google.com/?ie=UTF8&ll=4...,0.013797&z=16 - it's between Dromore and Cline). The only problem is that you're either gonna have to walk 15 minutes to campus from there, or you walk to King and then take the bus to Mac.
There's also a 2 parking on King just west of the Sterling intersection. Fortunately after 6 pm you can just park on Dalewood without having to worry about getting a ticket (just as long as you park on the correct side of the street!).
