Sounds and scenes from the era of steam-powered railroad logging come to life at the Yosemite Mountain Sugar Pine Railroad in the Sierra National Forest south of Yosemite National Park.  From 1899 to 1931, the Madera Sugar Pine Lumber Company operated miles of narrow gauge railroad track. During that time, nearly one-and-a-half billion board feet of lumber were harvested from the forests. Five wood burning Shay locomotives hauled massive log trains to the mill over the extensive rail network.  Today, the Yosemite Mountain Sugar Pine Railroad is a restoration of the old narrow gauge Madera Sugar Pine Lumber Company Railroad. A section of the original rail bed has been reconstructed using the same techniques used at the turn of the century. Two vintage Shay steam locomotives have been brought in from the Westside Lumber Company and restored to provide authentic motive power for the trains.  This one-hour narrated daytime excursion will be a great thrill for two adults and two children.  More info at http://www.ymsprr.com/
