Evening air is growing crisper, and days are filled with sunshine and the water is still warm enough for swimming. The busy season is winding down, but there are still plenty of events to attend. September gives us all time to breathe and reconnect. The Nantucket Island Fair, an ideal event to gather with friends and family and remember the simple pleasures of island living, returns on Saturday and Sunday, September 21 and 22, from 10 am to 4 pm.
