I have no data to back it up but I don't think a casino would do well in the North Country or Lakes Region. Seasonal maybe, but year round I think would be bust.
I think a casino near the Kittery Outlets may work as people would shop and then throw some money at the casino.
For the record, I could care less is someone wants to spend money. Having formal probability and statistics training pretty much ruins any chance for me to gamble. Been to Las Vegas and I spent $20 in the casinos over four days. I'm the free-loader type whom they probably want to kick out of the place
