ParkWhiz is a Web site that lets you reserve a parking spot via the Web or your cell phone. Think of it like OpenTable for parking spots; you pay for the spot, and simply hand your e-ticket to the parking attendant when you arrive.
Currently, ParkWhiz currently operates in over 2 dozen cities, with a focus around major sports arenas and airports. If you live near a supported city, you can make your reservations on the ParkWhiz Web site before you leave the office or access the site via a mobile app on your phone. [via TechCrunch]
