I make models for a few reasons. First I like working with my hands. If I'm not building models I'm messing with model trains, slot cars, etc. Second, it's a way to do a "deep dive" into a particular subject. Lastly, building models gives me an excuse to buy reference material, DVD's, etc. because I can say I'm doing research. "Honey, I'm making this Fokker DVII model so I just HAVE to buy these two books."
