I'm not a ratting man, but can't knock those that are - I understand having a passion for the dogs! This might seem a little far fetched, but there's a real opportunity for the right guys here. There's not many a place better to aware people than this forum either. South Georgia is a seabirds paradise. Its also a British colony plagued by rats. So much so, that they've just hit the headlines for the largest ever poison and eradication project.
