I do all my gun hunting here In Illinois from ground blinds. I it all day in a folding lawn chair, heater at my feet, hot tea thermos and hot soup thermos. Then when I really want comfort, I pull out a samich in tin foil and heat it with my heater and have a hot samich with my stew and hot tea!!!!! have been doing it like this for going on now 10yrs and have my wife to thank for that for she suggested it when we hunted together. Haven't looked back once!!!! Have taken some really nice deer from it as well. Took the first one at 25yds with ML with her in blind, just haveing bought it the night before. 141" 10pt backed up into a honeysuckle patch and brushed in. They work!!!! I use the Ameristep DogHouse. Rain, snow, wind, cold, don't care.
