up... but most the guys selling these systems often underrepresent how often you get "backed off" by casinos. They say "when the deck is plus 9 then bet 12x your normal bet".... how often do you think you can do that before a casino backs you off?

So sure... if you want to drive around to every tiny/gross casino in the country and try and take each one of them for $2k over two or three days... and you want to basically live on the road for months... and deal with the swings (even card counters lose) ... then you can make ok money before you get banned at every casino in the country.

But you'd make more in that summer doing summer sales. If quick money is your goal... just do summer sales. I'd bet that summer sales guys make way more than card counters.
