North Point Marina in Winthrop Harbor is the BIGGEST marina on Lake Michigan and certainly one of the biggest we've seen. Yep, count 'em...1500 slips. It is in the middle of a state park facility so getting to the store, etc. is a chore in itself. There is a pretty nice restaurant across the parking lot from us. Laundry and washroom facilities are located on every other dock. Boats boats boats everywhere...and weekends seem crazy with them...though we've not seen more than 7 people total here during the week....mostly just us and the birds!!!! We took a short dinghy ride to a beach on Monday only to be greeted by biting black flies and CCCOOOOLLLLDDD water...seems the prevailing winds blow surface water to the eastern shore...where the water is definitely warmer. We didn't stay long!!!!
