Take My Nephews First Time Fishing - Union county - Need Some Advice

[GDubya07]

Hello all - never really post in the freshwater section ( Lurker )
mostly in saltwater but need some help

Not looking for super secret spots - just something in general to take a 6 and 9 year old for a couple of hours. I know some of the basic spots but haven't really targeted anything in Union county in over 20 years (grew up fishing the rahway river in union by the old money store off of morris ave and the bridge in springfield on 22.)

Regardless I am looking to drop a couple of lines with my nephews ( this will be there first time fishing ever ) and just looking for a solid spot to take a couple of little guys fishing for the first time. Just looking for some action and get the nephews goin with fishing

Any suggestions would be greatly appreciated

Thanks everyone
