	Actually, I'm surprised that someone hasn't tried this already.  My
guess is that it would work if the structure provided sufficient surface
area and protection from the elements.  I wonder if other cues might not be
important, including color.  I don't get the feeling that chicken wire alone
would be very successful.

	Anyway, it sounds like a simple enough experiment - but I don't know
how a researcher could pull it off without upsetting someone on this list...
