Has anyone used nocturnal nightmare feeders? They seem like a great idea, but I'm wondering how to keep rain out or if they drain well enough to keep the corn from turning bad? Also, I've heard sometimes varmints can get stuck in them.

If you haven't heard of them, they are like a trough you can program to only open during daylight hours.

Personally, I do not like any feeders. If you get a sick deer, feeders seem to spread the disease because of the saliva of the sick deergetting into the healthy deer.
