Thanks for the compliments. I'm originally from upstate NY, and visited many parks like Watkins Glen, Tahonic(?) Falls, and others... all rivers or streams running amidst great walls of slate/shale covered with moss, ferns, and little trickling springs. That was my inspiration... things are very different here in texas, our lawns don't even stay green unless we water them more than is reasonable. That, and I'm a geek, tinkerer and perfectionist. I've had to scale back some of my plans as I went, but overall I think it's turning out quite well!
