one thing about the casual players i found in oregon is that they hardly ever raise with a bluff or draw on the turn. or not too often on the flop with a comp0lete bluff.
it isnt too easy to play against them as they call way too often as well. you have to have a better hand unless you very carefully pick your spots.
the big thing about this is that in any place you play it is important to figure out how you are going to play your hands according to the players that live there.
