Airplanes.  Pure and simple.  From my earliest childhood (at least as far back as I can remember), I've loved airplanes, really anything to do with aviation. I was building plastic models in grade school, and my dear mother even allowed my to hang them from my bedroom ceiling with fishing line.  As an adult, I got away from my passion for a long while, having kids and making a living, then a few years ago my interest was re-kindled with a plastic model I received for Christmas.  I eventually got so involved with plastic models that I was building them competitively, and won two 3rd place awards with a couple of my models in my very first competition.  Next came a radio controlled model for my birthday, I'd always wanted to try R/C but had never been able to afford it, and from there it was downhill all the way.  I tell my wife this isn't a hobby, it's a disease.  It's called "Hobbypox".  I can't help it, I'm really just a victim.  ;)
