I have gotten the bug to do this since DG member 'bluespiral' posted a link for it in the seed trading forum. It seems to be very easy to do and will be a whole lot easier when I know where I've planted 'those' seeds. I could see the lightbulb flashing and the little 'idea' bubbles forming. It will be better too, to do it after things are frozen and most little critters who like the seeds are asleep in hibernation so they don't 'collect' my seeds.
And yes; I will try winter sowing some tomato seeds; as I've seen volunteer tomato plants in downtown Binghamton near the supermarket, by the fenced in part of their unattended grassy area were the trees grow. The supermarket sets up their plant sales in front of the fence and also overloads of 'fresh' veggies in the warm weather.
So I'm posting the link here in case anyone wants to try it or talk about it.
