GSL Slip Renters and Marina Users. If you do not need to come out to the marina today, don't! We are experiencing a heavy blizzard with icy conditions. But please don't forget to come out sometime this week to check on your boats. I'm sure there will be a lot of snow in the cockpits and maybe some clogged scuppers.
