That cheat sheet is great! Thanks!

You're both very welcome. Glad I could help. I've been using the cheat sheets for some years now and they do come in very handy.

Enjoy your trips. We've never been to Niagara and love waterfalls. Maybe we'll get there one day. We saw the gorgeous Iguazu Falls in Argentina last year and have seen a few falls in Hawaii. Ain't Mother Nature grand?
