My outdoor electrical outlet has suddenly stopped working. Any suggestions?

THANKS EVERYONE! I reset the red GFI button on another outside outlet and that did the trick. [...]

Want to create a rock garden with a fountain – suggestions?

I would like to cover my back yard with a rock garden or with some kind of stone, and also have a pond or fountain somewhere in the mix. Any ideas, websites, photos, suggestions? Thank you.
