Southbound on the Chicago flyway just off-shore in very nice weather at about 2500' MSL. There is another N/S flyway to the west that threads its way through the suburbs but this one works best for my route. After passing Gary we climbed up to 15,500 and had 30-35 kts of tailwind headed back to N.C. I sometimes see other opposite-direction sightseers on the flyway but not often. Up high above the Class B, there are always heavy jets not far below going in and out of O'Hare. O'Hare approach talks continuously.
This is when flying is nice.
