To answer your question about landing zones etc. you have to set your decoys, or in this case position yourself to suit the wind. In a big spread you set so the birds will follow leaders up into the wind past your position to the main spread. There is an art and science to setting decoy's. But if they really want down bad they will land around you while your standing up in the set. But 98% of the time there real fussy.
I would imagine that spread pictured is left out from day to day except for daily changes due to wind direction. Illegal here but perhaps not there. Then again could all be a pile of BS like the fella says. Sure has my 20 goose decoys beat anyways.
