If I'm seeing deer I don't eat at all.
But if it is slow or I'm not seeing any thing I'll grab a beef stick or pop-tart from the pack, & I always take water.
Bacon and or sausage and biscuits, coffee, and cigarettes unless it's saturday and then it's cigars instead of cigarettes.
I get to watch movies on my phone too.
In case you think I'm kidding...NOPE. That's the routine.
Last big buck I killed my jersey glove was on fire. LOL!
I use the "Shock and awe" routine on them. Deer is smart so I "Psyche 'em out" by acting like I'm not hunting
