I just saw a show on the travel channel i think it was on this. An hour long and hella interesting. They said the hardest part in the beginning before the casinos had any idea what was going on was getting the money back home without drawing attention. I dont know if simply for tax evasion purposes or what since they won it legally but the one dude said once he had 650,000 on him going through an airport and another set of guys had over a million dollars. They would bring back a lot in chips too I guess so it wasnt all cash and they said sometimes they would have problems with airport security scanners thinking the chips in their configuration was some kind of bomb.
