It depends on where you live. Canning makes more sense if you are living in the city in a apartment complex where things like generators can't be run, and might not be allowed. (storing gas would be an issue) A freezer would stay frozen for a couple days without power, and if the climate is cold enough you can put in on the balcony in the winter.
Plus, canned meat just isn't that great. I don't think this article was about how to survive a disaster, but more about how to save money on your food bill assuming everything else is normal.
The article was more an ant/grasshopper story vs. Repulican/Democrat comparison, but OK.
Oh man, one of the best things I ever had was pickled Dove breasts. A friend of mine bagged his limit and gave them to his wife. She cleaned them and pickled them in small jars.
One night after a few beers we raided her pantry. We knocked off about half her stash along with a bag of pretzels. She pretended to be mad but we all ended up laughing about it because she caught us red handed and with chins dripping.
