Checkout the links that I have provided.
First is a link to the Worlds Greatest Hobby Campaign. This is a joint venture by the big names in model railroading to promote the hobby. Much information is available here for the beginner as well as the novice. I am an ambassador to this program and enjoy sharing the hobby of Model Railroading with others.
The second link is to the Corona Model Railroad Society. This is a group that I am currently the Vice President of. This group was started by the Historical Society in town to recreate Corona as it was in the 1940's. The goal is to portray what impact the railroads had on the development of Corona.
