Just think of the insane amount of labor that would be required to manually sift through every inch of ten plus years of accumulated garbage searching for a tiny little object.
i think the garbage dump kept computer records of what zones they put garbage in in different time periods so they could narrow the location down quite a bit and not have to search the entire garbage dump.
i think he had a business plan for that and had investors maybe. not sure.
How many months or years would it take? Is he going to do it by himself?
it wouldn't take very long if they were just looking in a small area. probably months at most.
Doesn't matter how much money you throw at this wild goose chase at the end of the day, someone, or many someones, would have to manually sift through every square inch of the garbage in that zone. Who is going to do it? No one in there right mind will want to perform such a grisly task. Even if you somehow narrowed it down to one zone you're still talking about hundreds if not thousands of tons and years of accumulated garbage.
