Guide to Tailgating at Northwestern

I just set plans to attend the the NW game with some family in Chicago. None of us have actually gone to a game down there. Family lives in Wrigelyville area and we will be taking train/uber to Evanston. Are there any go-to spots or things we should do in the near or around the stadium? 

We planned on checking out the practice area right on the lake and just kind of walking around. Any tips would be much appreciated.
