There are several sheep in New Zealand. A friend's first reaction when he heard about the New Zealand plans was "hey man, you're gonna be a sheep farmer?"
so that's where they got the idea you find these in most livestock countries to get the animals up into a truck "lambs for slaughter"
but I never saw them in Europe at airports, they're called "bridges"
smart, they're not
but as a Carl Hiaasen character remarks, they're very peaceful
we humins am smarter than that... they need dogs or barbit why 'r'? to protect 'em... beeg shame!
