Topband: DXpedition Beverage Termination Grounding Schemes??

[Steve Harrison]

When on a DXpedition, and Beverages are quickly tossed and laid out
within several hours, how is the termination resistor "grounded" at the
far end, and the transformer at the near end; with counterpoises, ground
rods, or what?

And with either of those, how long and how many wires for the
counterpoises, and/or how many and how long the ground rod??

I've seen photos of expeditioners laying out Beverage wire through, over
and under thickets full of brambles and thorny bushes; but never have I
seen them laying out counterpoises or pounding in ground rods.
