> A few weeks ago there was a tragic caving accident at a local school here where a boy drowned when the outdoor adventure group entered the caves even as flood waters were rising from a storm.

That's awful, and if there's one thing that I learned from Thai cave rescue a few years ago (https://en.wikipedia.org/wiki/Tham_Luang_cave_rescue) it's that you never want to go swimming in caves when it might start raining.
