Personally I don't have a problem with them if certain restrictions were enforced. First, I would love to see a limit of 2 dozen PER BOAT. Second, I would require a tag with name, address, and phone number so that a fine of $50.00 could be levied for each unattended yo yo, and $100.00 for any fish left hanging for more than 1 hour. Third, they would have to be attended within eyesight from the boat and not from land. Last, they would have to be removed when not in use!
