Deer hunting, i used to start hiking up the mountain wearing nothing but long johns and boots at 4am to reach my stand by 530 (1 hr before daylight). This was VA public land in the 80s where you had hunting pressure even up high. We were crazy. Killed some deer though.

Boar hunting, Ive slept in a shooting house all night in Germany. Sometimes the pigs would wake you up and sometimes at sunrise you’d switch stands to hunt deer or drive your stiff tired self to work.
