Well, now that someone else is banking off my idea that I had 5 years ago.. I'm back to thinking about how I can make my first million. Well, I guess I will promote their site now, because its cool.
Type in a zip/address/point of interest, and this beta site'll kick back garage availability, free parking, metered spots, and permit restrictions.
Soon, they will have sensors to tell you what spots are "available"...
