There are many breweries ranging from small to large up and down the eastern seaboard. I am not sure on your exact location but I'm sure if you do a little research in your area you'll be able to find a few tours. I, for instance am in SW FL now but grew up in SE PA. Dogfish Head in Milton, DE gives a great tour. They also have a great restaurant in nearby Rehoboth, DE. America's oldest brewery, Yuengling in Pottsville, PA and Tampa, FL are both great tours but two very different breweries. I even know a guy who started a brewery in a storage facility in Tarpon springs, FL. In the past he has had volunteers come in and help bottle his brews (which are now being shipped all over the country. Once on a road trip I stopped off at the Blue & Grey Brewing Co. in Fredericksburg, VA on a whim. They were very personable and gave me a tour of the small facility on the spot.
