Brian Hart (36), Communications.
Brian is my link to the outside world when I’m away. He is also my brother in law, a fine birder and naturalist, a serious intellectual and often my voice of reason in hairy situations. (You should have heard him during last year’s blizzards!).  His dream is to one day devote the bulk of his time to nature photography and birding.
