Just thought i would post a reminder to everyone who has been practicing in warm weather, to put on a few layer of clothes and your hunting jacket and practice for awhile, it makes a difference until you readjust to all of your clothes, this hurt me a few times while i practiced with a t shirt and then all of the sudden im up my tree at daybreak and there is a frost and i have a shot and missed and wonder what happened just to find out that my form was different because of my clothing, now i make sure i shoot quite a bit with my jacket and a few layers under it.....
Good luck
