My dad used to take me to scale model conventions when I was a kid. He loved building models and he loved the conventions even more. It's a pretty obscure hobby so I'm sure he liked the company.
A ton of scale model enthusiasts packed into one space, sharing all their model knowledge and cool creations? Yeah, he was definitely at home at those conventions. By the way, you think they're all tiny but they're not. They're scale so some of these are pretty large. Take a look at the pics; maybe you'll join the model world!
