Rick, you are in zone 8, I am in zone 5... and we can grow quite a lot of things here, including tomatoes. (Well, some people can, LOL!). I think you should be very optimistic! Backyard Herbalist (I am going to have to call you BH unless you share your first name with us... too much to type!), you are in an even more challenging zone than me! But, there are many of us with northern gardens here... let's all see who we can bring on in to help! I do wish Dahlianut was around...
