No, and your failure to see this seems to cloud your reasoning. I have merely pointed out that the OP didn't come here asking whether to do something, he asked how to do it. He did not provide enough information for anyone here to criticize the choice to do what he is wanting to do, but lacking that information hasn't stopped many from seeing his post as an excuse to give advise not sought.
Which implies that the OP hasn't given this any thought and that YOU, without enough information to offer any useful advice, nevertheless have excellent advice to give.
So you are objecting to the pin placement you know little about? Or you think it is reasonably objectionable, again, without knowing much about it?
And, this misses the point. "Stupid people do stupid things" is a perfectly good defense to misplaced concerns about liability. You cannot prevent stupid people from doing stupid things nor do you have the duty, as a course designer, to try.
Translation: "No matter what you think, I am right." What I suggest is that anyone who, upon seeing a river next to or running through a park, and who wants the park moved away from the river because someone might drown, is unreasonable and very unlikely to be heeded by anyone.
Like, how likely? 52%? 77.3%? Are roads inherently dangerous, just like rivers, such that we have to make sure that people do not go near them?
This is just as silly. If any part of hole is anywhere near a road, discs will go on the road. It doesn't have to the the basket. Of course, this is also true of water. Does the fact that disc golfers may have to walk out onto or cross the road to retrieve a disc make the design dangerous? Of course not.
And yet, here you are.
