I am new to the bored (as of yesterday), so am not sure if this is the right place to post this, but has anyone tried this yet!!?? Go to google maps : http://maps.google.com/maps
Type in a location, and then click 'Street View' in the top of the map. Unfortunatly not every location has a 'Street View', but I have been able to locate a few sirens in Plymouth and Canton MI. The picture quality is surprisingly good.....
