No, we don't. And you have been reported for abuse under the catagory of..., gnome hunter.
Please ignore this response. It never happened.
Actually, humor aside, my mother often saw the "good folk" and was one of the sanest, most gracious and intelligent people I ever knew. She worked at the U.N., in embassies, for the U.S. government, and donated a great deal. I saw her get angry about three times in her life, period. She was a magnificent hostess, and so kind. Yet, despite being a member of mensa, being extremely pleasant and normal, she was utterly convinced she had seen them many times. Considering the other experiences we had with her and I have had myself, I have no doubt she did.
I haven't seen gnomes, but a few other things. They really don't want to be seen, and have the means to make sure that "you never saw them", even if you did. I experienced something like that myself, and managed to get enough evidence to make me wonder why it was such a hard thing to remember when so much evidence was right in front of us.
Good luck. Your Gnome Village was probably a tourist site, but I wouldn't dismiss the concept of other life on earth easily.
One who's seen.
