Actually, you're right about swans, LA.
One festie in France, we went off to a lake and did loads of acid. There were ducks and geese and a couple of swans. They look lovely, the swans, but they're just like raggas.
They just glided across the lake and whenever they saw a duck or goose nearby, they went after it and tried to mug it. Vicious båstards, imo.
