This past weekend, 630,000 volunteers joined together in Australia to take part in Clean Up Australia Day. By the end of the day, they had collected nearly 8,300 tons of trash from their streets, parks, beaches, and neighborhoods. In the past, Clean Up the World has encouraged its participants to use My Maps to chart their activities, but this year they did something particularly exciting: Clean Up Australia chairman Ian Kiernan AO visited several clean up sites and added photos and text to a My Map along the way with the new My Maps editor for Android using the HTC Dream phone.

You can see Ian Kiernan's map below, or read more about last weekend's event on the Google Australia blog
