Beginner in Secaucus - good places to fish? Tips?

Hello everyone, My son got the fishing bug from a friend, and he got him a rod for his birthday.

I got myself a small rod and we have been hitting the fishing deck in Laurel Hill, and Mill Creek Point Park. We tried Duck Pond once.

And we never caught anything :)

We don't mind to keep trying! But it would be nice to find other parks/spots just for variety. Around 30 mins drive from this area, maybe a bit more if we can spend more time. Any suggestions?

Thank you!
