In heavy hunting area, I often seen more elk during rough weather cause the human scents are wiped away, gun shots are silenced by the snow/rain, nearly all of the hunters are drinking coffee back at camp and not sure what the true reason is but some herds of elk just start to make big circles around mountains (maybe cause they're cramped up from hiding)
. Biggest challenge I dealt with is after wiping the glass down, make a shot before it fogs up again, even the leica BRF had a difficult time being visible. It was mostly from the body heat blowing a lot of moisture on to the glass. More adrenaline means more moisture! LOL
Congratulation on the drawing and good luck!
