I started Garden Railroading a couple of years ago. I think the best part of the hobby is that my wife loves it! She loves the trains running through flowers and the idea of a focal point to the backyard. Although, we don't have any grandchildren yet, it attracts all of the little kids in the neighborhood. I installed a small 5 x7 goldfish pond. The kids show up everyday in the summer to run the trains and feed the fish! Lots of fun and entertainment. The advantage of Garden Railroading is that the flora and fauna can support the railroad, rather than having to constantly build and add scenery and buildings as you do with an indoor layout.
