Engeman Theater in Northport for a performance of Goodnight Moon. Circus fans can see indescribable feats at the Acrobats Of Cirque-Tacular at the Staller Center For the Arts in Stony Brook. For some outdoor fun, head on over to the Annual Rockville Centre Street Fair where you can see artwork and classic cars on display.

Also on tap: Family Fun Day at the Broadway Mall in Hicksville, and Midsummer Night at Old Westbury Gardens in Old Westbury. As always, check our events calendar every day for fun activities for the family.

       I spend the spring months eagerly awaiting opening day, not at Fenway, but at Adams Park, where on the first Saturday in June, the Roslindale Farmer’s Market begins its summer run. Our farmer’s market outings aren’t just for picking up extra groceries. They are the first sure sign of summer, long lazy mornings spent on picnic blankets watching our daughter play with her neighborhood friends. If you don’t have a local market or farm stand you call your own, check out Tara's post from a few weeks back, or one of these three urban/suburban oases.

This cruise is sold out. Don't worry: Mommy Poppins will host other exciting events soon! Taking a cruise on New York Harbor is one of our favorite summer activities in NYC. That's why we here at Mommy Poppins are excited to invite you and your kids to a very special event we're planning: Ships, Sails and Tales of the Sea with Bill Gordh & Manhattan by Sail. On Saturday, June 29 join us as we set sail back in time aboard the historic Clipper City Tall Ship on a 90-minute excursion with family activities by master storyteller Bill Gordh, a scavenger hunt by New-York Historical Society's DiMenna Children's History Museum and more.

During this fun outing, families will board Manhattan by Sail's historical Civil War-era cargo schooner Clipper City for an exciting voyage out of South Street Seaport. As we sail through New York Harbor, we'll enjoy amazing views of the Statue of Liberty, the Brooklyn Bridge and other beloved NYC landmarks, plus there will be a stellar lineup of entertainment and enriching activities for children.

Read on to find out how you can snag tickets to Ships, Sails and Tales of the Sea with Bill Gordh & Manhattan by Sail—a day out on the water Mommy Poppins-style that you won't want to miss.

You don't have to be a fan of thoroughbred racing to thoroughly enjoy a day at Belmont Racetrack. The Breakfast at the Belmont program (that we recommended for Father's Day) is a great way to get an intimate look at all aspects of the park, before the gates open to the crowds. Belmont's backyard is equipped with a playground area, a duck pond, a concession area, and the paddock, where you see the horses just before the race. On Family Fun Days On Sundays bouncy houses, games, and activities fill the yard as themes and activities change weekly.
