I started in my early teens and I bought my kits at Thrifty's and Woolworths in California. Built mostly airplanes and military vehicles and just as I discovered and started to enjoy model cars (the Pintos and Vegas), I went off to college and gave it all up until I was in my late 30s, then I picked it up again and have never looked back. I think I build models now for the very same reason I built them so many years ago: for the fun, and also because they help keep my imagination sharp.
I don't build for others, I build for myself. I try to build what gets me excited, regardless of accuracy, etc . . .
LONG LIVE STYRENE!
