Yes Mike, anyone can tie up. You don't HAVE to check in with anyone as we don't have a harbor master or even a bartender on staff. If you want to be polite, check to see if anyone is in the club house and if so, let them know your intentions...we appreciate stuff like that. Or what I would do is leave a note on my boat with cell phone number just in case. Also, if possible, do not use the side of the dock used by those launching and retrieving boats.
Of course, if I'm there, first round is on me. Unfortunately, our liquor license says we are a private club for members and guests only so we are not officially open to the public but be my guest.
