The northern coast of California is redwood country. The size of these trees run from gigantic 2,000 year old granddaddies to 500 year old burly adolescents with girths up to a dozen feet across. In 1885, a logging railroad was built to move these massive redwood logs to the Mendocino sawmills. Now this slow old train is traveling the same rails past the same trees and it is delightful. We learn from our docent that in 1925, self powered gas rail cars were put into service which frankly stunk up the place. The locals had a saying, "You can smell 'em before you can see 'em," which finally explained the name of our train.
