daf bit: Kiddushin 29

[cellio]

Some commandments are binding on men but not on women, among them the following obligations to his son: to circumcise him, to redeem him, to teach him torah, to find him a wife, and to teach him a craft. Some say: and to teach him to swim. Rabbi Yehudah said that a man who does not teach his son a craft teaches him brigandry. (29a)

No, but you ARE required to build a fence around it, if it's a danger.

That would make sense, but there must be practicality limits. A fence around the entire Grand Canyon?

Of course, now I'm mixing and comparing the metaphors of building fences around the torah and a cliff, set to the proverb, "Good fences make good neighbors."

Clearly, I need more sleep.

If it's on your property, you are required to take reasonable efforts to make sure that it's not a danger to passerby. If it's entirely within your property, your responsibilities are lessened, but not eliminated.

If you lived next to the Grand Canyon, your responsibility would be to put a fence around your property, or, at least, the generally travelled part of your property, such that people on your property would not wander off a cliff in the middle of the night.
