There have been many threads and discussions posted on why/how you got into the train hobby; Why did you come back; Is the hobby shrinking; Is the hobby dying; etc.
What i would like to know is why you didn't choose that other hobby to pursue? I'm not asking what is there about trains that attracted you more than something else, I'm asking why didn't you pursue some other hobby.
I don't know what they all are but to name a few: remote car/airplanes; stamp collecting; wood carving; beanie babies; antiques; knives; guns; automobiles; plastic models of ships/cars; military dioramas; sports memorabilia; thimbles; picture art; books; baseball cards; postcards; etc. The list could get quite long.
In wondering why people, or young people in general do not get into the train hobby, we possibly need to understand why we aren't attracted to the other hobbies. Just a thought
