Listeners of the American Passenger Rail Heritage Foundation's The Let's Talk Trains Show suggested we visit the Taltree Arboretum and Gardens Railroad Garden in Valparaiso, Ind. So for this week's show, we will check it out. We will learn from the professional gardeners and model railroaders about their railroad garden. We hope to learn more about the building of the garden, it's operation and what Taltree's visitors think about the layout. Join the conversation about model trains and gardening, the two most participated hobbies in the world.
