Platial - Greyhound Bus Stops
Platial user Tmweber has created a Google Maps mashup showing Greyhound Bus stops in Missouri, Illinois and Michigan.
The Greyhound Bus stops are shown on the map with blue map markers and are listed in a pop-out window. Clicking on any of the markers loads the details of that stop into the pop-out window. The details include the number of the buses that stop there, the address of the stop and a link to its website.
FortiusOne's Maker has data layers for Greyhound Bus terminals in many states. If you want to create your own Greyhound Bus map you can use Maker to create the map or download the data in kml form.
