The OP has a very good question. So I'm going to offer a different perspective. While all of the answers here are basically never, mine is somewhat different. For me, and I'm I'm going on, hmmmm, uhmm 55, yeah that's right. I had to do the math on that, all this year I thought I was 53, when I was really 54! LOL! But back to the question, I've been giving it some hard thought lately, I don't have room for a layout, I just set up a carpet layout for the first time in umpteen years and while I liked it, the excitement just wasn't there like it was when I was younger. And maybe partially for that was because it was just that, a carpet layout. Crawling around on a hard floor and getting into positions or maybe I should say TRYING to get into positions I could 25 or 30 years ago just doesn't cut it anymore. I really like and I am still fascinated by trains, but lately I've been contemplating as to whether I want to keep collecting or maybe give it up. I've spoken to my wife about this and she's all for me staying with the hobby. She want's me to understand that she has no problem with what I collect or what I spend on trains, she's great on that. But for me at this juncture in my life I just don't know. I look at my PW Lionel NYC F3's and just love them sitting on a shelf, along with my many Conrail Units and cabooses and other NYC items and I think to myself, what do YOU want to do? And right now to be quite honest, I just don't know. I'm still very interested in the hobby, maybe it's because I don't have a running layout and I really can't see when I would be able to build one or get one going. But for now I'm sorta up in the air. I know people will gasp on my answer but that's the way I see it for now.
