RE: Not sure where this belongs...
We use to drive a old broom stick in the ground then take another stick and rub across it several times and the worms would crawl out of the ground and we would collect them to go fishing.I heard of people taking one of those old style crank telephones and running a wire into the ground and shocking the worms to get them to come out.....hmmm come to think of it I think years ago they made a metal probe you stuck in the ground and it was plugged into an electrical source and used to shock-up worms also!
