Welcome to the forums. I started building when I was five and I just turned 64. There was a year gap in building a couple times while I was over seas during Vietnam but otherwise it's been fairly constant. I build all types of kits but lately have been working steel ships because I can't handle the rigging on sailing ships anymore. I also build some science fiction and certain aircraft that squadrons I have been in have flown in their histories.
I also build vehicles operated by the U.S. Air Force Security Police from jeeps, cars, and trucks to our armored vehicles.
I'm also getting kits together for a collection of aircraft flown by the Thai military.
If you have any questions on subject background, building informtion and so on, don't hesitate to ask, there's a wealth of information around here.
