This is my first experiment with Google Maps. It is a map of a recent trip I took to Florida. The markers are where I stopped for gas. I have credit card receipts so I could look up the data after the fact.Useless Google Map Tricks
According to Jeff
Clicking on the markers pops up a little google balloon with some calculated data, like the number of miles since the previous stop, and my MPG for the previous leg.
Nothing too exciting, but now I have a feel for Google maps. Maybe I can come up with something a little more useful next time.
