More Reasons to Can

A third reason we should can is quality.  If you grew it, you picked it, and you processed or cooked it, you know exactly what's in it.  Can't say that about a can you pick up at the store.
A fourth reason to can is to save money.  There are about $150 in start up costs, however, everything is reusable except the lids.  I believe this cost will soon be offset by savings at the grocery store.
Emergency preparedness is a fifth reason for canning.  Almost all areas are subject to weather disasters which damage the electric generating and distributing abilities of the local power providers.  Sometimes, power outages can last for weeks.  In my area, the problem is hurricanes.  Although Cut and Shoot is far enough inland to escape the storm surge, there is still enough wind to bring down large trees.  We lost about a dozen large trees during Hurricane Ike, on nine acres.  Some of these trees will hit power lines, houses, etc.  At any rate, it's easy to heat up canned food when the power is out.
A sixth and final reason to can is that it feels ethical.  Food is an essential commodity that is limited in many areas.  It seems horribly wrong to throw away food, that could be preserved, when so many people are going hungry.

Canners on top of fridge

Besides, having the canners sitting on top of the refridgerator makes it look like I know what I'm doing.
