cold never used to bother me when i was younger.......but yesterday with the wind it was about 0 degrees out....my sorry butt lasted an hour....walked the rest of my hunt....i used to laugh at dad when he was cold......now i am right with him........another thing that adds to it is 3 years ago i started driving deer from 10am-noon(depends on the day) till dark.....and the drive leader sent me on a looong mountainous drive and got me a little turned around...youll come to an oak tree turn left type of directions...so unless i TAG OUT he wont let me drive...im his designated hitter.....and im one of the few that can set up the shooters, and can actually hit and drop my deer....so i only have to sit an hour...2 hours at the VERY most when i hunt with the guys at the farm.....and i hunt with them alot.....that added to me not being able to sit long
