Haven't had a youngster kill anything at my place for awhile and I'd like to change that. However, I'm old, fat, getting lazier every day, and I hate the cold more and more every year. So..... I've decided I'm going to build an Old Fat Guy Deer Stand that will be big enough that I can go along with any young hunters and watch the fun as it happens instead of hear about it later. I'm thinking 8X12 with the heater in the middle of one of the 12 ft walls so nobody gets cooked out having to sit by the heater. I want two large windows on each half of the 12 ft walls for a total of 4 and one on each 8 ft end so I can watch the action. There will be a reclining captains chair for me included and Yes, I know I'm being selfish, but ask me if I care. Now.... Here's where you herd a turds come in. Type of window, size, vertical or horizontal opening? Please tell me why one is better in your opinions. Type of heater, size, etc. Also, please tell me why. Insulated walls/roof or no? Door type? Any other suggestions and thoughts are welcomed. Within reason. I don't want to spend the next six months of grocery money to build it either so frugalness gets bonus points and cheapness with functionality gets a gold star. Thanks Guys! Let'er Buck!!!
