This spring has been a time without transition. Normally on Nantucket, we are given a few holiday weekends (the Daffodil Festival in April, Memorial Day in May) to acclimatize ourselves to the influx of people who descend come summertime. That is often the hardest part of living in a place so seasonal, to remember the new rhythms that summer brings and adjust yourself accordingly. But there were no sneak previews of summer this year.
