How do they react to flashlights?

I've only been at this for the better part of four seasons.....but as far as "experience" in how deer react.....I get to see a LOT more than most. 4 seasons hunting them......+/- 800 deer sightings.

I've left everything from hats, to binos, shirts......dropped NUMEROUS items from stand over the years.....and I just can't recall a single deer reacting negatively to something I left or dropped.

I think their nose is where we get busted most times (if they don't see US).

Just a differenc eof opinion. That's all.
