Wimbledon is over for another year. However that's no reason for you to hang up your racket. Tennisopia is a Google Maps mashup that can help you find a tennis court in your vicinity.
At the moment Tennisopia has mapped a few major cities in Canada but has plans to expand its coverage. To find a local tennis court you just need to enter your address and the results are displayed on the map. The map markers indicate whether the court is public, a club, a school or in a condo / apartment block.
If you click on a map marker you can get driving directions and you can view further details about the court.
