If you live in Vancouver you now have no excuse for forgetting to put out your trash for collection. The city have developed this Google Maps mashup to inform residents about when their trash will be collected.
The map shows the regions for the city's trash pick-ups. If you click on a region you can then download the pick-up dates to your Google calendar or to Outlook. It is also possible to set up Twitter or email reminders informing you to put your trash out the night before the collection is due.
