Interesting that the rounds went up in 1930. I'm guessing that since the market crash happened in Oct. '29, maybe a few folks were unawares of the deepening and length of the trouble to come, so they went out to play golf in their spare time. Was there any private clubs in Portland at the time. It would be interesting to see if the membership fell of in that year or two following the crash, and those folks showed up at the public course for a year or so, until they fell deeper in with the rest of the downtrodden, and that is when the rounds fell off for a long time.
So, will public courses rounds increase next year, near the big financial centers where mid level managers have been members at mid level clubs, and give that up but not the game, and go play at some less expensive muni's for a while, and then the whole things slides downwards for 10 years? Who the hell knows.
But, it is a wonder how those courses with less equipment and products to apply to their turf, stood up to that many rounds per year of stress.
Lastly, is the guy on horseback under the presumed shot LOP some version of a forecaddie?
