RE: Deer have disappeared!
I haven't had time to look it up but I heard of a research study done in Iowa (I think) that tracked whitetails throughout the gun hunting season to see how far they moved. The conclusion was that the deer didn't move far at all they justdug themselves deeperinto swamps, thickets, etc. to avoid the extra human contact.
They seem to vanish around here from the start of shotgun season till the end of black powder season too so I know what you're going through.
