Shrek
WKR
All my experience with them is from the late eighties and early nineties and as far as I could tell the main ingredient was hydraulic cement. Instantly plugged me up. If we were only going to be out for a day or two I just wouldn't eat or I'd take some crunchy peanut butter and Ritz crackers. I'd eat the dried fruit dry and that was it. I have heard that they got a little better but I'll try not to find out. Mountain House is so much better and lighter. That pork patty was truly awful.
