<p>Paula Rhoads, producer of Brainiacs, videotaped the rough road coming down from the Alpine Tunnel for fun, which includes a lovely view of the Palisades. In order to accommodate the railroad of 1880s, engineers built without mortar some roadbeds where there is nothing below them. So far, they have held up quite well, with only a few stones dislodging in the last 130 years or so. Fortunately, Paula and her family survived the ordeal and beautiful scenery near Pitkin, Colorado and plan to go back as soon as possible. You can share some of the Pitkin footage occasionally on Brainiacs, which is LIVE at noon Saturdays on Denver Open Media, Channel 56 in Denver or via the Internet at www.denveropenmedia.org.
