Hi sinu Here are some piers on the Jersey side of the Hudson below the GWB http://users.nac.net/chasstamm/hrfanjorg/access1.htm
Parking downtown Manhattan can be costly. I think there is a municipal lot there but Im not sure of the price. Some people who fish there live in the area and or take the train. There are piers on the Manhattan side but I doubt that their listed anywhere. Most are private property and or delapidated. Livetofish fished there successfully last year.
Oh and congrats again for being our 500th member.
