Would it make a difference if I've said I've skied, biked solo, rock-climbed? If so, why should I have to do so when others don't, and are trusted to make up their own minds as to whether your property works for them?
Do you feel more confident than I am in determining my own limits?
Disclosure: I've been denied many opportunities because an unqualified person determined what was and was not safe/possible/healthy/OK for me to do, and find it upsetting to be denied my agency because of it. Glad to see these changes landing. If I've misinterpreted your post then I do apologize, but it looks like you're making choices and denying opportunities for capable adults, and I'm not OK with that if that's the case.
