By DENNIS WYATT 209 Living JAMESTOWN — You may never have been to one of California’s most unique state parks — Railtown 1897 — but the odds are if you are 50 or over you’ve seen glimpse of it as well as the railroad tracks that run into the nearby Sierra foothill countryside. If you watched “Petticoat Junction”, “Bonanza”, “Rawhide”, “Gunsmoke”, “Father Murphy”, “Lassie”, and “Little House on the Prairie” then you’ve seen snapshots of Railtown 1987. The same is true for movies such as “Back to the Future III”, “The Apple Dumpling Gang”, “High Noon”, The Gambler”, “Unforgiven”, “My Little Chickadee”, “The Great Race”, and the 1956 version of “The Lone Ranger.”
