Our computer guy has a friend who started a Canada Goose chasing service (not sure he is still in business) People on lakes hate them and can make the property unusable with the droppings.
He works with his dog, a pit bull. They spend all day together. Seems like a perfect life.
Our old business investor lived on a lake and their association hired a guy to rent swans (with clipped wings) for the summer (they chase off the geese).
