Because i didn't get enough of Cowboys and Indians as a child, nearly 40 years ago
It's a great release - a way to combine nature and the outdoors, hiking, a social and competitive activity, and to challenge yourself physically and mentally in the process .. all the while enjoying it. There are just not that many activities that involve so many diverse skills, experiences and opportunity for exercise in a fun package, as airsoft provides.
I'm in my mid-40's now .. never did paintball, and only started this airsoft thing last year. I only wish that airsoft had come up on my awareness radar a long time ago.
