Christian,
Your son sounds exactly like me as I grew up airgunning..
While my folks had a really big yard, and big enough basement for shooting paper targets,
I always used to venture off into the woods near by, state land woods, abandoned buildings, etc..
The crazier things to shoot at, the better! I say 'as I grew up', but, I still do that to this day!
I'm a Toys R Us Kid that'll never grow up. lol
Speaking of wandering and shooting..
Apparently that's pretty much the idea behind field target / hunter field target..
All these years, and it wasn't until' just last year that I even heard about that!
What I wouldn't have given to have known about that years and years ago..
You guys definitely had a lot of fun, and it's awesome that you filmed and shared!
Things like this most definitely make for some really great memories!
