Low frequency hum,then low flying helicopters,very often.
Helicopters flying low every night around Cliff Cave County park(1/2 mile from river),a lways preceeded by very low frequency hum,felt in the inner ear more than heard.
Then the intrusive low flying choppers. Today a black helicopter(visual) hovering @ 350' for more than 3 minutes. This is very weird.
