Once it gets warmer.. try going to the Watchung Reservation.. once there follow signs for the loop. It's an awesome play area... with climb on things and lots of slides and tire swings. It's great to pack a picnic lunch.. and within walking distance is a little place on the property too.. that is a museum with stuffed animals.. and then live fish, snakes, bees... and a whole lot of cool stuff. Because you have young children.. you should check out the Crayola Factory - it's in PA.. not to far.. maybe a 45 minute ride... has all kind of things to do with kids.. and it's fun. good luck.. and welcome to New Jersey..
