Having grown up in a lower 48 urban area it amazes me how we ignore the obvious solution of commuter rail.  Here we have tracks in place and actually run a commuter train between Anchorage and Palmer during the State Fair.  It should be easy to set up a daily run as an alternative to the crowded Glen Highway.  Once in Anchorage we have tracks in place to the airport (so far reserved for "tourists only") and more rail running south toward Girdwood (or even Seward).  Are we so addicted to our automobiles?  Heck, we had more public transportation by rail in the 1940's & 50's than we have today!
