Phil -
Thanks for your post & the link. I was not aware grass court tennis had arrived at Sand Valley.
Back in the 1950's and 60's, the competitive tennis "circuit" played 3 or 4 tournaments at various grass court clubs in England leading up to Wimbledon and the same in the U.S. and Australia leading up to those national championships (which used to be played on grass) in those countries.
Grass court tennis, like links golf, was once upon a time the rule, rather than the exception it now is.
