Planning on going to the Oregon game in September with my wife (we are planning a whole trip to the Pacific Northwest around the game)

Does anyone know the best way to go about tickets or any groups that organize and figure out the logistics of creating an Ohio State section at the stadium? I just don’t want to go on stubhub, buy a ticket, and then end up in the middle of their student section. Not much of a road warrior so wanted to see if anyone had any suggestions. 
 

Also, if anyone has anything that is must do in Washington or Oregon let me know. Thanks. Go Bucks.
