I keep an old broken trail cam as my bait camera.
That's a good idea...I have a Bushnell for just such an occassion
I almost threw mine away at the end of last season, good to know they can still serve a purpose!
besides as a bait cam, once a year or so Dicks sporting goods offers a $30-$50 trade in value (working or non-working cameras) toward the purchase of a new one.
