According to one of my friends dads who went to school here and more than likely would know something of this nature there is a small field in the refuge that is used for growing weed. You cant get there by foot but supposedly you can get there by taking a canoe or small dingy down one of the streams. When I asked my friends dad why no one would know about it he said that its pretty heavily gaurded and it is supposedly used for medical research and the grounds that it grows on apparently has some of the richest soil around. He told me how to get there so am prob gonna check it out when it warms up...anyone else heard about this
