has a good list of local home brew stores.
My parents live in Westchester so I went to the one in Eastchester. It is in the basement of a hardware store.
They had everything I needed except they were out of Hydrometers(they said more were comming in tomorrow). I just got the heavy stuff (bottles, carboys, etc) that is expensive to ship and mail ordered the rest.
My advice is to call ahead.
I hope to brew my first batch next week!
