Bay Shore’s first-ever installment of the summer music festival Alive Bay the Bay drew thousands to Main Street Wednesday night.

And GreaterBayShore contributing photographer Jennifer Mercurio was there.

“What a turnout!” Mercurio writes on her Lasting Impressions Studio blog entry about the event. “I think I can safely say that this event was a huge success that met and exceeded all expectations.”
