I've heard of using a 5 gallon bucket, take a broom stick or wooden closet rod and drill a hole in the bucket just larger than the rod or stick. Then run a nail/screw through the top of the rod to make a T and insert it through the top of the bucket so the nail keeps the rod hanging in the bucket through without falling through the hole. fill the bucket with corn and hang it from a tree limb. the deer will hit the rod with their nose to release the corn. I have several feeders that I use but a friend told me about this which is more portable and cheap. My friend has used it for years and I'm going to try it this coming season. No pictures yet...I haven't built mine.
