Yeah, they expanded the official tailgate area this year and it's still packed most games.
I havent heard if the Riders are having Riderville this year.
I always thought the Bombers should send up a drone on Banjo Bowl to capture all the activity around the stadium.
As you mentioned, most people dont see all the tailgating that takes place as they are so spread out around campus.
If you are going to the game from your hotel and want to save a few bucks you can take rapid transit instead of an uber/taxi.
There is a bus stop across the street at the arena and the stadium bus comes by every 20 minutes on Saturday.
Just make sure to take the Blue line to the UofM and not St Nobert.
It's just over 30 minutes and 3.35 per person.
Edit: this bus uses a rapid transit corridor for a good portion of the trip so it avoids most of the construction that Booch refers to.
