Cold frame gardening, long term food Options

[rainygardener]

I live in the higher elevation area near Mt. Hood Oregon, so I have a really short growing season and mostly grow cold crops and russian heirloom tomatoes due to their ability to thrive in cold climates.
This fall I have started cold frame gardening and founf some great articles on line. THere is a family in a colder area of Idaho that built a cold fram on the south side of their house and put 4 black water barrels around it. The barrel heat during the day and keep it from freezing at night. They grow nearly everthing but corn in it. Cool idea. I use heirloom vegatable seeds I purchase through Baker Seed Catolog and Seed Savers, then save my seeds year to year and make a compose pile. Gardening all this food is nearly free and gives me many options for food storage and money saved.

Thanks. Were the barrels inside the cold frame or outside of the cold frame. Seems to me they shold be inside.
