Double click the .zip file and it will extract two files. One is a .GDB Garmin route file and the other is a .GPX GPS exchange file. If you have a Zumo or other capable GPS, you can drag the .GPX file onto your GPS and the places will become POIs (Points Of Interest). OR, you can just double click on the .GDB file and it will open in Mapsource and the places will be waypoints.
I have to go right now, but I will try to put together more detail instructions with screen shots.
