A lot depends on the starting point while fleeing the Egyptians. Sinai makes more sense, and having been to the top of that mountain, the power is still very strong there.
Also, the Burning Bush is still inside the monastery - and it is the only one in existence.
That was a possibility also.
Actually Sinai is still a part of Egypt which is why I ignored that land mass. But it’s still a possibility I guess. I was really going more by what the article was talking about. 🙂
