This was on the edge as I drove up a road in Pontarddulais. As I was parked just passed it with my window rolled down, I was holding the camera on the door, since I knew it would fly away otherwise. In any case a guy came out of the house next to me asking me what I was taking pictures of (in a sort of argumentative/protective way). I told him what, and said as soon as you walk out further it will fly away.
He did, and it did.
Still he was genuinely chuffed.
