Here is a great tool for tracking my APRS activities. The map below, generated by aprs.fi will auto update showing my current location. This, of course, is only if I have my APRS radio turned on while I'm mobile or doing other activies.

Another note about APRS, this is the original Twitter! If you don't know what twitter is then do a search on the internet, you're bound to get a few million hits. It's the current biggest thing. But like most things, they existed in Ham Radio years ahead of it's time!
