StreetShuttle
 

Travel related businesses I'd like to see: StreetShuttle.

You find a free parking space on a city street near your favorite airport (that is good for the duration of your trip).

You call StreetShuttle and they come to whatever parking space you found, pick you up, and take you and your bags to the airport for a $5 fee. When you come back, they take you to your parking space (within a certain radius from the airport) for a $5 fee.

Sure, you could call a cab, but try getting a cab to take you on the return trip to someplace that is very close to the airport!
