Massachusetts Tollbooth Locations in Google Earth

One of the best government GIS sites has to be the State of Massachusetts MassGIS portal. They have a ton of shapefiles for almost anything you could need, plus building footprints for the city of Boston. Here is a Google Earth KML we file created from the MassGIS 'Tollbooth' layer which shows the locations of interstate tollbooths in the Bay State.

By providing this kind of base data, it allows for anyone to create additional value added products. By displaying this in Google Earth, we can share the shapefiles with users that would never load a true GIS package.

What experience have you had with other States? Perhaps you could share your info in the comments section.
