I only make it to one, maybe two home games a year now that I don't live in the state, but the upper parking lot is always the place to be. It seem like more people are tailgating earlier than ever these days. Last year at homecoming the lot was full by like 930am, if you want to be guaranteed a spot, have someone show up with the car by 8am or earlier, with the griz in town, all bets are off. there is a line down the middle of this parking lot, as long as you're west of this line, and drinking out of a keg cup, cops will no hassle you. If you are seen with an open beer, you could be subject to a ticket and/or arrest. Cheney only has a few bars in town and I'm sure all of them will be cracking by late that night. Again, I don't live in town, but here is how it usually goes.
Goofy's, The basement, Bill's Tavern - mostly college kids. (though went i went to Eastern Bills was a shithole old man bar, but then it burnt down and was rebuilt into a propper watering hole.
The Eagles Pub (formally Showies) - 10 years ago, this place was mostly filled with college kids, but the owner is an asshole, started charging a cover on big nights, and is just a general prick, these days this bar is mostly filled with 40+ year old locals, but i believe they have karaoke on Friday nights, if that's your thing.
there are always good bars in Spokane, the bar scene is pretty good (what else is there to do on a Friday night in Spokane?

). I'll let one of the other guys tell you where to go there, as bars are always opening and closing there.
As always, house parties are easy to find, just make some buddies in the tailgate area, you'll certainly find a lot more if we happen to beat the Griz.
The best breakfast in Cheney is at Willow Springs, which at least used to be owned by the same prick that owns the Eagles Pub, but even better, bring up something to eat to the tailgate area.
PM me if you want when you're up in Cheney, I'd love to meet you. I should also be tailgating in the upper parking lot, I’ll be there early.
