My final project for one of my classes is on "Google Geocoder Web Service: Overlay Data on Maps Using XSLT, KML, and the Google Maps API". I'll use this fire station data as my sample data. Actually I have some more plans too. I'll assume this following list is correct, but there may have been changes/additions/deletions since I made it.

When I finally get around to making the map I'll grab whatever info is on the county pages. If there's still some edits I missed just let me know and I'll fix it.
