Do you know where he might be visiting in Montana? As Steve says there are poker games (and chips) available in the larger cities like Missoula and Billings. If he's going to Billings (not likely if he's visiting Idaho, long ways) I can give you some ideas. And, I'm sure Steve could give you plenty of information on poker games in western Montana (bordering Idaho) since, rumor has it, he frequents those kinds of places from time to time!!
