One of my favorite places to take pictures is Waterfalls of Dreams.
As far as I know they don't have a Flickr group or website or even a lot about them at the landing spot, kind of a beautiful mystery. You will see a lot of pictures taken there on my Flickr and on this blog. It's just lovely and you can ride beautiful horses there! Here's a link to their page on the SL website, the slurl should work, if not lemme know in comments!
