Other weird links: here's the StreetView car passing some kind of weird truck with cables and tanks on it: https://maps.google.com/maps?q=beltsville,+md&ll=39.030349,-...
Turn around to find the "Area Under Video Surveillance" sign (surveillance? for a corn field, a barn and a forest?) https://maps.google.com/maps?q=beltsville,+md&ll=39.030268,-...
