Well, I didn't find this because I'm a Floridian. :) The reason I know about this site is because she featured my fireplace under styrofoam art. You're absolutely right that you can spend hours enjoying many things here, in addition to getting some good information. She really does find things that are a feast for the eyes. (And I don't believe she's a Floridian.)
Don't miss Andy Goldsworthy on Inspiration Green. He's one of my favorite sculptors, so I was glad to see she'd included him. I have the DVD of a beautiful documentary on him. If I remember correctly, it's called Rivers and Tides. Most of his work is ephemeral: leaves in streams, melting ice. Even though he's done some more permanent things such as stone walls, even they are intended to change because of trees growing near them. Fascinating.
