Having used both will stay with the ground blind
until cant crawl into one best of all when its cold
raining,snowing etc.makes for a comfortable time!!

tree.

I like using a tree.

Tree if the terrain and cover allows.

tree definatly i usually put out 10 or so stands and then jump around with my climber.

Most of my hunting experiences have been in treestands. I have also purchased a pop-up blind(doghouse) recently and took my 8yr old son hunting for the first time. Something I would not have done in a tree stand; kids are too fidgity, won't see animals.
I have recently acquired one of those "leafy suits" in ASAT that I want to put to the test by ground hunting for deer stealth style; just me and the bow.
We'll see what happens, but the upclose and personal thing has to be a rush.
