Recently the city (taxpayers) had to pay out a half-million for a settlement in a drowning incident at Falls Park. Part of the settlement was putting signs at Falls Park. The solution was two wood signs, NOT by the Falls themselves but in the parking lots. I will admit I did not go down closer to the Falls to see if there was more permanent metal signage, but if there isn’t this is where it should be.
I have often been on the fence about this, because I think people need to watch their kids, and if you injure yourself or die in a public park it’s kind of on you, several laws back this up. But I also think safety measures can be put in place, but no amount of signage will encourage common sense.
