DT, thanks for posting the Newport article which I missed. Garland, that article about George Bayer was fascinating--I'd never heard of him. And it is notable also for the use by the author of the word "Brobdingnagian" to describe Bayer's length--paging Terry Lavin!
Yet there is no getting round the fact that in the mid 70s hitting the ball 275 in normal conditions was considered a big whack.
Sean, I don't disagree with you that more of us can hope to drive a par 4 or make a par 5 in two than in the old days. But I have to agree with Shivas and Garland that 275 was not considered a "big whack" in the mid-70s. At that time in Sacramento, I was a kid playing Northridge CC, which had (and still has): #5, a 445yd par 5 that us kids us to hit in two regularly; #7 a 309yd slight downhill par 4 that we would be disappointed if we weren't pitching at most a half-wedge to; and #9, a 493 yd par 5 that we were often nearly on in two shots.
At #5 the second shot plays over a little pond, so you had the classic risk-reward calculation. It was a tough chance if you weren't at or beyond the 200-yd marker with your tee shot. As you've emphasized, it was fun to have that opportunity--it's a well-designed hole, and I was frankly pleasantly surprised to see when I looked it up just now that it's still called a par 5

I can't recall what kind of balls we used back then--they weren't balata, too delicate. But there were plenty of guys who could hit them 275 yards.
Alas, I'm not sure whether to laugh or cry at dragging down memory lane--I can't hit as far now as I could when I was 15!
