That's how I practice casting (w/yarn) in the yard, alley and local parks from time to time. Neighbors always ask if I am catching anything. I say kitties. Ours is a decidedly dog neighborhood. The birds like our yard a lot, maybe cause I feed them too. I know Harry Lemire fished occasionally (for awhile at least) with clipped flies. No hook part. The grab was drug enough for him. But I'm not aware that he fished out of season. I doubt it.
