RE: ground blind vs. treestand
Short answer - I prefer setting up in a tree stand. My guess is that since about 1975 I have hunted 96% of my time from a tree stand of some ilk. However tree stands are not always practical, and sometimes flat impossible for the lack of trees!
I often use blinds. Total enclosure blinds can provide at least some relief from tough weather, and I am convinced I can get away with a bunch more movement when I am in a ground blind, as long as I am quietly moving.
