At a holiday event at Pershing Square in Los Angeles in December 2009, the Angels Gate Hi-Railers Model Railroad Club of San Pedro (AGHR) shared the fun of model railroading.
This movie (3:41) illustrates the both the interaction of the public with the model railroad as well as the ambiance of the surrounding activities - all of which brought smiles to young & old alike.
