I have hit a toddler in his mother's arms. It was a blind anny shot, on a 700'+ hole, so a big bomb turnover shot. I was using my 2nd run Valkyrie (VERY SHARP) and didn't even see the people when I went out to make sure it was clear (as we always did)
Threw one of the hardest, lowest shots ever with the perfect amount of anny to turn the corner and it would flatten out, heard a THUD, and then bloodcurdling scream. I sprinted up to see what happened and I had hit the little kid on the right bicep, while his mom held him, probably 100' from the tee pad. On a shot that would have been 400'+, so it was still traveling very fast.
It was 100% my fault. I threw the disc that hit the kid. It doesn't matter that I looked and still to this day have NO IDEA where they came from. I thanked all the lucky stars that this lady and kid were OK (it was only about 12" from her face hitting the kids arm)
All you people saying it isn't our (disc golfers) fault 100% have never hit someone for real. That happens you understand it was your fault. You NEVER are forced to throw your disc. As soon as you choose to throw, you choose to accept all responsibility for that disc and anything it does.
I have skipped more than a couple holes in my life due to people not knowing what disc golf is, not understanding how badly they could be injured, and not wanting to get out of the way. It isn't their requirement to know that, it is mine.
Analogies to a ball golf course are silly. Even public ball golf courses are in completely enclosed (even if by rope) areas dedicated to ball golf. I have only played a handful of disc golf courses with that type of set-up.
Baseball fields, soccer fields etc: If you do not have a reservation for the fields, and they are mixed use parks (ours don't even have outfield fences, just backstop fences) then it doesn't matter that you want to play softball and they are having a picnic. It is a mixed use area.
If it is truly a mixed use park, then the ones throwing the deadly weapons are the ones who are at fault. (softball, disc, golf ball, boomerang, kites, anything)
