I know this has probably been brought up before in here but...I love to hunt, I love the outdoors, I love the cold and I love deer. But I cannot sit up in my stand or on the ground for more than 3 ½ hours. I have tried everything. I know you can stalk deer and do other types of hunting but I like to stand hunt just to be able to watch the animal do its thing and not a have clue in the world I am there is an awesome feeling for me. Anyway does anybody have any good tips to help me stay in my stand longer, and keep me alert longer. Any help would be appreciated.
