Um, about GMO seeds not being available to the home gardener, they're certainly available to me and I go to great lengths not to buy or sell them. There are only 2 or 3 strains of non GMO sweet corn available, for example, and only one farm that has actually tested their seed for contamination. Golden Bantam is all I am sure about so that's all I sell.
Once GMO pollen has floated over your fence, some of your crops contain the patented genes. (This is how Monsanto sues organic farmers and puts them out of business.
It takes effort to avoid GMO's. If you don't trust Safe Seed Pledge companies like mine, buy seeds from SeedSaversExchange. But we're trying. Really. Heirloom seeds may not be perfect, but they haven't been tampered with (and they're way cheaper because no one owns the patent.)
I'll get off my soapbox now and go to bed.
