Did you know that you can make and save your own maps on Google maps? You can draw on them, link to them and use them in trial. Here's a quick one I made of the path from MPD to the courthouse: Courthouse to MPD. You'll need a free google account. Once you have an account, you will see an option for "my maps" whenever you visit google maps. Click on that and then "Create a Map" and the rest will be fairly obvious.
