AVON-BY-THE-SEA - The final "unofficial" week of summer has arrived and for many families, it's the last chance to get away to the Jersey Shore before school starts.

Annemarie Colwell is with her family for a week's vacation before she and the kids head back to class. "We're both teachers and we're getting ready to go back to school," she says. "We get together every couple of weeks to walk the boards."

Bob Hilton of the Jersey Shore Convention and Visitors Bureau says the week before Labor Day is also a crucial time for New Jersey's economy. The crowds who come to the beaches and boardwalks are vital to the region's economy. "It's very significant, especially if the weather holds out," he says. "Because this is a good indicator of how the fall is going to go."

Tourism in the state's four coastal counties brings in an estimated $20 billion a year.
