I think these guys are still around:
About Feather and Fly Sporting Traditions - An Orvis Top Ten Dealer
One of the owners use to head up the local TU chapter there.
There used to be another one, Choo Choo Fly and Tackle, but I think they went under. You could try calling to see if they still have the lights on.
