I hear ya, that is why I have a gnome free garden...don't trust those buggers! :DCheers!
The best garden gnome I ever saw was in a UFO gift shop in Roswell, NM. You can probably guess what it looked like. I wanted to bring it home, but my wife wouldn't hear of it being in her garden.
Alien gnomes i could see in my garden, alas you have to keep the Wife happy. :)
These are right creepy. My bro and his wife have some in their yard.
