Which brings us to my point, which is that finding high ground is good for at least six things, not limited to, but definitely including: reading a book, launching a blitzkrieg attack, defending against a wicked enemy with a horde of soldiers at her command, avoiding a flood, and hiding from tall polar bears, which is a potential situation worth considering. Also, you are closer to rainbows.
