HaHa. Well I am not near the ocean but I am not too far from a military base.
It's quiet here where I live and rarely do I even hear a helicopter fly over....when
I do it is usually one of those med vac choppers.
Where I lived before moving here, I lived very very near a military munitions plant.
There would be choppers flying in there day and night over my house and/or over
the fields near my house. There would be louse KABOOM'S that would shake the
entire house at times. That base was there for many many years. Then one day
it went KABOOM! super loud. Someone goofed and blew the whole place up.
Several died and they never rebuilt.
Where I live, the biggest threats are earthquake and tornadoes. I live on a fault line.
