Grandparents Day will be celebrated Sunday, a Sept. 7 event every year since President Jimmy Carter signed the proclamation that created the holiday in 1979. Here are some ideas for grandparents and grandkids to make the day memorable.

Dine alfresco Show the grandkids that no matter how old you are, life is still a picnic. Pack a nutritious lunch and head to one of Long Island's many parks. For a list of state parks, go to nwsdy.li/liparks.

Arts and crafts If the weather won't allow for outdoor activities, think about an afternoon at a museum or art gallery. Find one near you at nwsdy.li/museums or nwsdy.li/galleries.

Mall and multiplex Shopping for some last-minute back-to-school supplies or taking in a kid-friendly movie makes a wonderful bonding experience.
