"All my friends .... late 20's and early 30's ..... think I'm kinda strange for playing with these expensive O scale Lionel and Atlas trains, anyway."
Same for me too........but now, many who thought that way are scrambling to acquire an engaging hobby as the key to health in retirement......they marvel and delight at the layout (home or modular) and I am constantly asked for advice on Starter sets, for when the grandkids come over........
....and, by all means, come to York if you can......99% of the people are great.....As in life, there are that <1% we could all do without, and being treated poorly from such peopelwill likely have nothing to do with your age...
