Within the past couple of months I've been reading stuff online about the Navy's plan to create a large weapons training area dubbed the Northwest Training Range Complex. It originally extended from Washington to Humboldt County and would encompass vast stretches of open ocean, as well as including some land-based operations as far inland as Idaho.
There is an article in yesterday's Ukiah Daily Journal about the Complex, and apparently, it's been expanded to include Mendocino County.
