Nice catch David. Stuart Bendelow has the same quote about 'science of a lifetime" and use of indigenous grasses on page 149 of his book on his grandpa, Bende.
I've often described my early childhood living next to and old Bende 9 holer, with a second Bende upscale CC nearby. The name of the course next to our house was called Burr Oaks. It was of course greatly populated by old burr oak trees that Bende deftly routed around. And, those trees were old and huge. It seems all the other Bende courses here in the Wisconsin area that I've seen were also designed among the trees. This isn't a case where trees grew after design, because most of them were big enough to be 100+ years old in the 50s. I think of Bende often when I walk among groves of burr oaks. I believe we share an affinity for them, even on golf courses...
