Since Presque Isle opened in Erie, I've stayed away from Seneca when I'm up your way. PI is only an hour away from SA and the BJ has far more favorable rules.
The thing that amazes me is that many of these stores don't realize that they need to compete with eachother. A casino won't make up it's shortfalls in profit by increasing house edge, they will make it up by lowering house edge and telling everyone who will listen that they're doing it to get them to come to their place. Yes, AP's will come and take some of the money, but the average Joe will outnumber the AP by at least 100 to 1 and still lose a boat-load of money. He'll keep coming back though, because the store is offering him a better chance to win and he will occasionally win. He'll remember his wins and tend to forget his losses and tell friends of his wins and help the casino to recruit new patrons to "beat" the casino.
AC is prime example - They are headed for the toilet because they refuse to compete with the PA casinos who have siphoned off a large % of their customer base. They actually thought the PA joints would be a joke....a fad....that would go away and not something they had to worry about long term. They now realize they have to worry but rather than try to woo gamblers to AC with a lower house edge they make the games worse to try to compensate for losses. This will ensure their demise unless someone with a brain takes over a joint and starts to compete.
