Welcome. I am lucky I can play games at home with our son (when he is on leave from the army) and our grandsons (aged 10, 7 and 6) who are all keen on the Hobbit games and the oldest on LOTR. Look for our Callum and Grandad posts here.
I'd suggest joining a local club and attending some of the wargame shows in Scotland. Not many LOTR games on show but there are a lot of clubs present so you should be able to find one that has at least "someone" who plays. The next big show is Claymore in Edinburgh on Saturday 5 August

BTW we are in Livingston, West Lothian.
