thanks for all the help guys, I assumed that the #10 can meant 10 lbs. wow was I wrong. I did the calorie calculations from the mountain house nutrition information, and there is about 2,000-2,500 calories per can. only a days worth of calories. I think I will get a few for long term storage. (there advertising says 30 year shelf life) and then go the other route you all suggested, it sems to be better cost wise. Thanks again.
