sorry but i have to disagree. flying over the top of ohare is not a
good place to be. if you dont believe me check out the STARs, most have the
inbounds crossing various fixes at 30 to 40 miles out at 11,000 ft.

I've been flying VFR over the top of O'Hare for the past 20 years. Almost no
traffic up there. I find all of the traffic below 10,000' and above 4000'
around the sides of the class B. But then again, I transition over the top in
excess of 250 knots. For slower VFR, I'd recommend lake shore or the west side
as previous posts have described.
