The Chicago Bears, one of the NFL's charter franchises, has some of the most dedicated fans.  This is evident with thousands of Bears fans in attendance at the wildly popular Bears Training Camp, held annually in Bourbornnais, IL on the campus of Olivet Nazerene.  I made my initial trek to Bourbornais last year and was pleasantly surprised at the wide open area and the access being in close proximity to the side lines.  

I was able to walk right up and snap away at the action on the field.  If you are a fan who is willing to arrive early, wait in line for about 2 hours, and set up right up on the sidelines with a chair and cooler, you won't have to worry about having your view obstructed by hats and heads.  I just prefer to just wait in the car until the line dies down before going inside.
