Fall in Long Island is for apple and pumpkin picking, and if you happen to be near Southampton, we highly recommend you take the family to Hank's pumpkin town. To get into the main attraction area there is no admittance fee. Hank's knows the more fun you have, the more likely you will buy pie and pumpkins.
And there is no shortage of fun or pumpkins here. Giant wooden play structures dot the area. Some are reserved for the older kids, but others are perfect for your one year old. Breath in the fall air, pick up some of the delicious kettle corn, and take a lot of pictures.
