Roy, do you mean hot hunting, or hot weather, or both.......
I will be in Idaho for Elk on the opener for 12 days then down to AZ. for Muleys In Jan. If I am lucky maybe NM.
Defintely the "hot weather". Nothing like chasing after those balcktails in 105 degree heat. However, I usually hunt later in the year until it cools down to 90 before I chase after them.
