I had an uncle that had a 40 acre forest on the outskirts of the lower mainland. Logged selectively his whole life, bragging each year he would get 5/8 growth rings per annum. Sold the back 40 for 10 times more than he ever made logging.
SnG, the plot you gave the Kal RS must have been remote…I think we only have Engelman spruce here. Sitka a coastal variety?
