so much private land has been logged and replanted since then.. in those days we would buy a 40 lets say for 150k  take 200k of timber off of it then sell the land on contract for same price then hypothicate the note to pull out more cash rinse repeat.. we also would use our logging roads and staging areas stratigically so when we left the roads were in the right place to do a 4 way lot split and the landings/stagging areas became the building pads.. in the NW permits for logging are not tough.. in those days it was over the counter and there was nothing you needed to do with regard to excavation.. however if I just bought the land and wanted to put in roads and pads then I would have had to get a grading permit and all the survey and engineering that went with it.. its was really something how we did that.. and I miss it to this day.. the other item that made it so profitable was Japan was paying premium for Export quality doug fir logs.. you could get double or more for export logs.
