>>213063533 (OP)Anton had a point. If he spied the satchel shortly after this, then why didn't he immediately clamber down there to get it. OTOH I can think of one good reason: it's right next to the border checkpoint, and he doesn't want anyone watching him. I think his idea was to wait until dark and try then, feeling it was safe in the tall weeds until then.
This random depositing of a satchel along a certain path compares directly with Fargo. Both men are killed before they even have a chance to retrieve the money. And in each case the satchel could easily be lost track of in the given natural setting (some anonymous snowbank on a rural road, a large field of grass next to a river).
