Gag. MRE. Meal, Ready to Eat. Three lies for the price of one. They were better than the previous field rations, I'll grant that.
We found a recipe for hard-tack and made some. It made me glad that I didn't serve in the Civil War. FYI, the last barrels of hard-tack from the Civil War were used during the Mexican wars. In what? 1912? Blech!
