It has not bothered me in the past when people fish my slips. But I can't have undersized fish left in the basket so I am going to lock up the entrance and give the combo to my friends so they can still fish. Shame one person has to mess it up for everybody else but I don't want to pay fines for undersized fish and the game wardens check this marina slips on a regular basis, looking for untended fish in baskets and on stringers.
