Welcome to Idaho John. But like Devon said all of us live in the Northern part of the state where it has mountains and lots of trees. The Boise area of Idaho is more desert and farm land. You might check with the local hobby shop down in that area after you get settled in. One of our former members lives down in that area and there was a club at one time, but I don’t know if they even exist anymore.
Our club is located in what we call the Pacific Northwest which takes in the Coeur D’Alene, Idaho and Spokane, Washington area. We currently have over 30 family members, with most having backyard layouts. We meet the third Saturday of every month at a members house to run trains on their railroad and enjoy everyone’s company. You’re always welcome to come visit anytime and as Devon said we can always find a layout to run on. We also have a web site that you can check out it’s www.inlandnorthwestgardenrailroadsociety.org
