Hey nysteelieguy,
Your post caught my attention because I used to fish for Big Browns when I lived north of NYC. I was most successful in the Fall... Mianus River, CT, Cross River reservoir, and especially below the **** on Croton Falls Reservoir. My arms were wasted taking Browns on wet flies below the **** in the no admittance area. That was back in the 60's... today is now... Spring... and I'd bet you can still be successful!
If you can afford a guided trip.. do it! Several years ago, I paid a guide for half a day on Lake Erie tribs and learned more from him than I had in the previos 10 years on my own! You may not take a Big Brown... but you will learn alot for the Fall!
Mike
