RE: What do you carry in that Backpack??
Holy moly!
Look at all that "stuff". You guys carry lot's of stuff.
I just started using an Outhouse blind this year and leave it set up since the first day of the season. I have started using the bag it comes in to carry some "stuff" back and forth from there. I use the blind kind of like a base camp really. When the weather is so nasty I'd stay home otherwise I hunt out of it.
Inside the blind I leave a climbing treestand, travel coffen mug, chair and a set of shooting sticks like Varmint Al makes.
I somtimes use the bag from the blind instead of loading and unloading pockets and carry a thermos and extra sweat shirt, sandwich, maybe some Mtn Dew. Carry out what ever needs to go back in it.
