Any tailgate parking lots in Edmonton??

Quick question; Im headed to Grey Cup this year and wonder if there is anywhere to have a tailgate party? I don't mean a sponsored one where they sell you food and drinks. Im talking like we do in Lot J. Out of the trunk, with our own coolers, BBQ's and pop's. I'll rent a car if there is REAL tailgate parties. I sure there out there. But, how far from the stadium, do a lot of people tailgate and what is it like???
Thanks you guys! I want to make this one to remember!

I live about 10 minutes away from Commonwealth (walking time). If there are any near the stadium, i'm not aware of them. The City has a big Park and Ride lot serving the LRT station across the street, but that is closed off for shuttle buses on gameday sadly.
