Somewhere in the teens but temps are not what kills me. Wind and rain when its cold bother me the most. Sitting up in my comfy tree house makes it tolerable but strong wind makes the whole stand sway.
My least favorite hunt was only around freezing temps but it rained all day with gusting winds. It rained so hard that night it was hard to sleep in the pole barn. It wasn't insulated at that time and the sleeping quarters were not finished. My only comfort that night was a warm place to relieve myself.
