We all know that shore revenue is an important part of New Jersey's overall tourism economy. But what about the state's historic sites? Some experts say the Garden State struggles to capitalize on heritage tourism.

Despite the recession, tourism remains big business for New Jersey, with $38 billion of the nation's $1.2 trillion coming from the state.

The problem is how travelers view art and history nowadays.

"The interest of visitors has changed in recent years and it may not be that there is less interest overall in heritage tourism, its that heritage attractions sometimes don't always create buzz and crowds" said Amy Webb at the National Trust For Historic Preservation.

"New Jersey has a rich heritage full of notable museums, icons and events. Its one of the nation's oldest and most populous states," Webb added.

She says it may come down to art galleries and museums looking for financial help to increase hours and visitors.

"Many states these days are experiencing a heritage tourism crisis, where since the economic downturn, people may not want to spend money on these things. It could take a little thinking outside the box to make some attractions more interactive for families with more to do for the kids."

New Jersey was the nation's 9th most visited state last year.

"The state can do more to bring in revenue from historic sites, but it will take some work," said Webb.
