There is a section to the right of the page which allows you to sort by location.
Click Mid-Atlantic and New England.
I'll add to it though:

Not sure if you normally get beers from Cali, but some of them are shipped to the East Coast. That would be the other Beer Mecca -- some available Breweries on the East Coast include: Firestone Walker, The Bruery, Green Flash, and Ballast Point.
