To Can or Not to Can

I always feel like I should be canning something when this time of year rolls around. Not that I, personally, have ever canned anything, or even have the slightest idea of what canning entails. All I remember is that there are big pots, hot water, glass jars, metal lids and tons of food. How all those ingredients get combined to store stuff up for the winter is a total mystery to me. I guess it's slowing turning into a lost art, huh? Who needs to can food when you can just pop over to whole foods for some yummy sushi or soup?
