Sounds like you need one of the Game Cameras like my DH got to put up at his tree stand!! He hasn't been out to put the card back in it or new batteries for a while, but it is so fun! I think he paid $40 for it at WM. Maybe less. It has a sensor on it and takes pics when it "sees" movement!
I've not been on much lately. Just been busy. THe kids keep getting sick, and we've (DH and I) been catching it, too. Strep, bronchitis...we've also had our share of viruses, too. Hopefully the computer doesn't start catching it! lol!
