I don’t recall seeing any signs telling me how many people have died on the roads I drive everyday.
You can die participating in any sport. Every sport has a certain level of risk and you know those risks before you participate. That actual risk is often reduced by the knowledge gained from previous injuries or deaths but you can’t remove it all. I wonder how many people have been killed in route to Dutch Springs. You might as well make them liable for those also. If I dive in a local lake from a public access and get killed, can my family sue the state because they provided access? Seems no different. Now if I was killed because the dock collapsed on me while entering the water then I would think there would be case for neglect.
