Chris, Matt....you guys have been at this longer than I. Disagreeing is fine. You both may be right.
I see a LOT of deer most years.....and I get to observe a lot, too. Maybe my deer aren't pressured? I just don't know.
My thing is....I don't give them much credit in the "smarts" dept. Extremely good at surviving? Given. I just think they'd have to learn to do the looking up thing.....and I don't think they're capable of such. Heck they haven' tlearned to look at two headlights and avoid them, yet.
