Back when I was creating my short-lived bowling tournament locator website, I always thought I would have a tool where the user could see all the tournaments within a given ZIP code (or set of ZIP codes) by displaying them on a map.

How cool would it have been to be able to actually outline and display the ZIP code boundaries on a map? OK, not very if you are not a geek.

Anyway, Matt Berseth has developed a way to do just that using ASP.NET AJAX and Microsoft Virtual Earth. Check it out.
