Bev, the liability alone is one of my main fears of having people around. Then you also never know when a visitor might have a disease on their shoes or clothing. Then you have to take in consideration the animal rights movement. I had some one slip in and open one of my porcupine scages two years ago relelasing over 20 porcupines. I want to do some night time photography and do some serious data collecting with my flyers. Like which feeds produce the best litters averages, diet effects on mating, foods eaten most. There are thousands of questions to be answered once you figure out what to ask....I would like to get some actual footage of them breeding, maybe a couple live births, Like I said there are so many directions I want to go. My pens are going to be colony pens with real trees & natural looking nest boxes.So the possibilities are endless as to what I can learn.

>Bev, got your e-mail but I am on the way out the door
