Have I piqued your interest with the above title?
What on earth does such a topic have to do with model railroading?
I respectfully submit that the answer is: a lot.
At least it does for me, and I suspect it also does for at least for a few of you.
A Fount of Creativity; that's an easy one to understand. The hobby is so multi-dimensional: design, construction, benchwork, track work, wiring, electronics, structures, scenery, repairs, restorations. I can go on and on.
Creativity is involved in all of these components of model railroading.
IMO, there is no activity that stimulates creativity more than model railroading, but some that involve as much creativity. Examples are music, fine art (painting, sculpture, etc.), and photography.
Model railroading can interconnect with other highly creative pursuits, such a photography, fine art and music. For instance, one of my peak model railroading experiences was to paint a backdrop thereby combining our hobby with fine art.
Now, it's time for you, who are so inclined, to chime in on this topic, after which I will share with you the genesis and inspiration of the other portion of the above title. Arnold
