Encroachment, Encroachment, Encroachment. Coupeville OLF was established in 1943. Ebey’s Landing National Historical Reserve was established in 1978. So the Reserve, and all the other Johnny-come-lately property owners around the OLF, are the problem, not the OLF. The OLF was there first. How stupid does one have to be to establish either a Reserve or a homestead next door to an active airfield, and then complain about the noise.
