When I was a kid, I had an N-scale layout; well, I still have it stored away since it was something me and my late father put together, its hard to part with. My N-scale engines were ruined when a leaky roof soaked them. Fortunately, N-scale trains aren't expensive. These days, my 2-year old daughter (who loves trains, BTW) has given me an excuse to get into G-scale - something I could never afford to do when I was younger. Right now, we just have the typical loop under the Christmas tree, but we're busy figuring out where our garden railroad will run and I'm busy saving up for all the expensive stuff we're going to need to make this happen.
