On the week following Labor Day, traditionally the “Cream of the Crop” of RC flyers in the United States and Canada gather in Detroit for what has become to be known as ” The Experts Contest”.
...
The week after Labor Day has to be the week of 10 - 17 September so the weekend of 16 and 17 September.
Cees,
"The week after Labor Day" in 1962 would be the days Sept 4-8 (see 1962 Calendar
here), as Labor Day is the first Monday of September (in 1962, it would be the 3).
The weekend in question would have been Sept 7-9.
Hope this helps.
Andy
