Fishing with kids in Central or Northern NJ

[fishingwithkids]

I'm looking to take my son fishing, and am looking for recommendations on places in central or northern nj that might be good for shore fishing. He's 6, likes to fish, but as all kids do he gets bored with no bites. I don't need any big fish, just something to keep the 'fishing bug' going, as we've had some luck recently. I'm not very familiar with good places as I did not grow up in NJ myself, and would appreciate any recommendations.
