I remember my first kit very well.
It was the early 80s sometime and I'd been bugging my mom for a model, I'd seen some of my friends building models and it looked like fun.
One day in a toy shop, I saw a 1/72 Monogram Snap-Tite F-4 Phantom and I just had to have it, my mom gave in and I had it together within 10 minutes of opening the box. I flew it around the house for a week when I figured it would be better painted.
After painting and decaling, I hung it from my bedroom ceiling, within a year it was joined by a Revell/Crown 1/144 B-52 and Revell 1/48 F-16.
My early models are all gone now but the memories and the model bug remain.
