hau Benton, I think you are on the right track by seed saving, building your own
land race tomatoes gives you the opportunity to select for the plant behaviors and tastes you find most appealing.
Who knows, you might end up with a tomato that could become an heirloom in the future.
One of our current favorites is Cherokee Purple, but it has issues for us.
I started to cross it with our other favorite (early girl) this year. The first years seeds will show if I want to continue crossing these two next spring.
