Unless the van has gps or their phones pinged or a half dozen other ways the feds can trace their whereabouts.

GPS and pinging off a cell tower to triangulate your location works fine in the civilized world.

Out in the deserts of UT/NV/ID/CA there may not be any cell towers to ping off of.

There is a whole lot of nothing out in the SW US.
