I grew up in Spokane, and Mc Q's is a great place to play. (Or at least it used to be as I haven't been in quite some time) The 7th Rail has 6 8' Bar Boxes, and they have good weekly Tourneys, and some good players.
Not sure about Spokane, but in post falls or in coeur d'alene Idaho there is some action to be had. Only a hop and skip from Spokane accross the Idaho border.
I go to spokane 3-4 times a year, I just don't make it out to McQ's very often. (It's been about 3 years) I usually do shoot in the fri-sat cheap tourneys at the 7th Rail when I am in town.
Spokane and that whole area don't really have a pool room, Mc Q's tables are shit, so you're going to have to look for bar tables to play on, and most of them are shit in that area as well. The Falls, in Post Falls, ID is a major league bar, but not a money spot, good luck!
