XAML Football Pitch

Here's a XAML football pitch, potentially the beginnings of a Silverlight football application. I've used metres as coordinates, and drawn a pitch of the maximum allowed size. For the second penalty area, I just reflected the first one. Unfortunately there is no simple way of reusing the same item twice in the same XAML file.
