With all due respect to the Jemsek family and what they've done for Chicago golf, but Cog Hill does not evoke in me the same feelings as Pebble, Merion, Olympic, Pinehurst or Oakmont. With the recent movement to host at courses that are accessible to the public, the only real options in the Illinois area are Erin Hills or Whistling Straits.
I play Cog on a fairly regular basis and although I like the course, it does not have the wow factor I'd expect from an Open venue, whether its measured by history, scale, difficulty or strategic interest. Its a fine course and worthy of a tour stop, but its missing the extra intangible that makes the courses named earlier special.
Erin Hills may have that quality, we'll see once people have been able to play the new layout. Hopefully the USGA will see the light and set the course up to play to its strengths, namely thats its supposed to be more Irish than American.
