Freemason Semi: Hauling FEMA Coffins In Wisconsin

Are these more of the so-called FEMA coffins being hauled in Wisconsin aboard this ‘Freemason’ semi-truck in the video below? The Freemason symbol is clearly visible on the front of the truck. These boxes do not look exactly like the coffins exposed by Jesse Ventura in Conspiracy Theory and shown in the picture above, but look similar. Are they some other type of underground vault? The structures clearly say ‘grade line’. Could they be underground electrical vaults? What do you think? Are these the dreaded ‘FEMA’ coffins? My personal opinion is I think that they are some other type of underground vault. Caution! Very loud noise do to wind.
