after college i also lived in Fair Lawn for a while! right on Fair Lawn Ave by River Rd. i didn't really start using saddle river county park until I lived in elmwood park later though.
since we're on the topic of fair lawn and fishing... you guys all know about the ancient indian fish trap in the passaic river right there, right? it's the V that sticks out of the water at low flows just upstream of the fair lawn avenue bridge. they've been fishing that section of river for a LONG time!
