I don't have a hydration bladder in my pack. I do have 2 extra magazines and a box of 50 in it. Change of clothes, 3 pair socks. 9 MRE"s. Water purification equipment. Good boots next to the pack. The pistol and two magazines is secured in a strong box hidden in the car near the pack. Hopefully, I can get to the car if I'm at work. I'm 43 miles from home, parking lot to driveway.
Two days.................without too much trouble.
