That's a no, can't do it again, they no longer issue open rubber processing licenses, ASEAN put a stop to them, as they feared local rubber companies could not compete in an open market.
I just got here at the right time, no real roads, very little electricity, no phones, no rubber, every thing was at bargain basement prices.
Then the rubber flowed and money was everywhere, people who never had money were buying new cars, building new homes.
Strange in some ways, seems this area of the land border was marked for development, speculators moved in, prices climbed and have not stopped.
In the nearest town, Buntharik there was not one motel 10 years ago, now must be over 20 small resort type places and building continues at a pace.
Sort of lost it's magic as a unknown unseen area, can't stop progress I guess.
