Montauk Daisies

I'm on Cape Cod in Massachusetts, and have noticed this white daisy everywhere.  I didn't notice it in previous years, probably because I wasn't looking for photo subjects then.  These plants have just started to bloom, in contrast to the daisies in Maryland, which bloom in the spring/summer.  These are Montauk Daisies, a fall perennial.  Apparently they bloom until frost, and love the sandy soil.  The one in this photo has a pretty visitor.
