Heck, when I was 10-12 years old we threw ordinary hatchets and knives at pine trees.
We also played "Split", a game where you threw your knife at the other guys feet trying to get close without hitting his foot
The idea was to get your opponents feet spread as wide as possible before he fell over.
And yes, occasionally somebody's foot got hit, but nobody was ever seriously injured. The leather shoes of the old days helped--"Keds" not so much
BB gun wars were popular too. You had to wear swimming goggles to play.
Of course our parents didn't approve of any of this stuff, but some of us didn't care.
Life was different and a LOT more fun back in the good old days!!!
We made an ax/knife throwing target at an archery club I belonged to back east.
It was made of a bunch of 6inch 2x4 pine blocs stacked so the end grain faced the thrower.
There was a 2x6 on the top and bottom with long lengths of rod stock on either end.
The rods had nuts and big washers so we could crank the 2'6s down TIGHT thus holding the blocks in place.
It worked very well and nobody was ever hurt--including kids of the families.
I'll go look at the place in Whitefish when I get a chance.
Given that "stuff happens", it's hard for me to see how one can get hurt
IF people follow sensible rules.
Personally, I don't approve of alcohol being served at a venue like ax throwing. I think that's
asking for trouble.
It'll all depend on how well the owners monitor the activity and enforce their rules.
