If you can, take a ride on a smaller aircraft over California. The first thing I noticed was almost everything is uninhabited. US Forest Service manages 20 million acres of National Forest land in California. Another large portion is state park systems. California State Parks began the 1990s with over 260 park units, 280 miles of coastline, 625 miles of lake and river frontage, nearly 18,000 campsites, 3,000 miles of hiking, biking and equestrian trails, and 450 miles of off-highway vehicle trails on nearly 1.3 million acres.
