Chuck or anyother heirloom expert, How much of a problem is cross pollination with heirlooms. You implied it is too much of a problem to use saved seeds. Last year I saved seeds from several heirloom varieties but didn't use cages. A gardening/C.S.A. friend told me they wouldn't come true so much to my husbands dismay I planted the saved seeds and also some newly purchased ones "just in case". We now have 145 tomato plants. So far I can't tell any problems with the saved seeds but here in WI there aren't many ripe tomatoes yet. I was lazy again this year and didn't build cages, do you think I should bother saving seeds or just wait until next year when I finally am more organized? Waiting impatiently for that first red tomato, Kim
