Riverhead Building Supply is more than just a lumberyard. They have numerous specialty items - wood, beautiful trimwork, special woods and lots of hardware. If you're working with wood, this is a great place to go rather than Home Depot because they really know what they're doing. I've gone, as a woman picking up stuff for a husband who told me SPECIFIC things to get (as I don't know what I'm talking about with this stuff) and they haven't looked down at me or made me feel uncomfortable and even helped me load stuff in the car. I really like this place!
