"Bonding Wire"(?) disconnected from frame under mobile home?

There's a bare copper wire dropping down from the service panel I believe -- couldn't see it exactly, but see now reason for the same to be going any where else. This wire was parallel and close to the big gray pvc(?) conduit housing the wires coming in from the pole.

So I google briefly for "mobile home grounding" and learn grounding for the home could be done at the meter pedestal (power pedestal?... a grouping of several home's meters and disconnects below the meters) outside the home, and the wire I saw could be a "bonding" wire.
Where does this bonding wire connect in the panel, and and is it potentially dangerous for equipment and occupants without it connected to the frame under the home?

Gone googling again right now, thx for any help!

Find the first whole-house disconnect switch or breaker, usually this is at the meter pedestal for a mobile home. A #6 copper "grounding electrode conductor" should connect the service neutral there over to a pair of 8' ground rods at least 6 feet apart. This GEC needs to be continuous or have "approved" splices, that is, splices that cannot be unfastened and refastened easily.

An additional #6 wire (this one called a "bonding jumper" in the U.S.) is connected from the mobile home frame to the panel ground or a GEC. So, via this wire, the mobile home frame is bonded to the ground rods. If A is bonded to B and B is bonded to C then A is bonded to C. (Meeting code does require components and wires used for bonding to be of certain sizes and materials and attached in certain locations and there are other requirements such as the kind of splices.)
