Hello fellow UK'er. Nice to hear your grandson is interested in the hobby and you are helping to encourage him! If it is particularly American he is interested in, there are quite a few clubs and get togethers focused on American in Devon and the along the soputh coast in general. Good luck!
Thanks. He is enthused by all at the moment so pretty much going to give him free rein with whatever he wants. It's going to be more a case of what to do with my own layout once it gets started! At the moment the horse's are, as usual, taking a lot of time so it has mostly been spending half the night watching YouTube videos and learning. Hx
