Thanks for all the interesting replies.
I never attended any event at Glenview.
In the mid/late 60's, I was in college and after college, I was completely out of model aviation until 1990.
Other things got in the way - career, skiing, windsurfing, motorcycle and car racing and such.
I guess I missed a lot.
I did, however, have one very memorable experience. In the early 50's, my Father took me to the nats at Willow Grove, PA.
The bleachers were full of spectators and the entertainment was provided by the Blue Angels, a B-25 JATO takeoff and the special guest was Jim Walker.
