I have some designs for one you can build yourself on my website at www.wilcoxwebworks.com/hs Look for the hog trapping page. Has a guillotine door made of wood that works well. Open top so deer can jump out. We have had a lot of trouble catching more deer than hogs in our totally enclosed traps. There is a guy in Camden that sells some very good doors too if you are interested in purchasing one. Call Park Harris at 334-682-4410
