Hey Tishman,
Be carefull those eighteen year olds tend to move back after they move away!!
I got started when I was about ten. My uncle switched from O scale to HO scale and my dad bought his O scale off him. I played with these for a long while but didn't have the space for an O guage layout. So I switched to HO and have been going ever since. I belive I am currently on my 15th layout not counting a few small switching layouts. Hopefully this will be my last!
