I don't. That doesn't mean I wouldn't try and help or encourage some youngun' who showed interest, but I'm not going recruiting.
No one in my family had any interest in trains, but I acquired one at a very early age....not even sure how, where, or why, but it happened. I think if it's meant to be, it will occur one way or another. The old "You can lead a horse to water, but you can't make it drink." applies, I think.
