@ninnymary , all gardening is local. People have good reason to talk about their "microclimates." We can
paint a larger area with broader strokes so that we don't all have to grow many plants of the same species and variety and select select
select over many generations to have the very best seed and genetics for our little plot of land. There is also the reality that every growing season can be different from those preceeding. Diversity is good insurance.
Choosing and purchasing seed doesn't have to be based on the glowing descriptions by retailers. I have complained on TEG about "days to maturity" quite a lot. Still, it is more than somewhat helpful.
I wish that Tomatofest had a store that you could visit. I don't even see a mailing address anymore, although there might be one on the cart checkout webpage. They are right in your area and once managed the Carmel Tomato Festival.
Tomatoes are the #1 garden plant in the US. Many people have a tremendous interest in growing heirlooms. Of course, there are also farms with commercial interest in the crop. The number of varieties is staggering. Some are widely adapted but diversity is there for us to enjoy

. It isn't guaranteed with any one choice, however. I have proven that with failure to ripen, disease problems, splitting and catfacing.
Tried & True can be a little boring. Experimenting can be fun! I look at those 4 of the 8 in the collection, none of which I have enjoyed in recent years, and think how it would be a treat to enjoy them again.
Oorrr, what about 1 or 2 of the other 4. I am no longer intending to have 60 tomato plants in the garden
buuttt having good food and fun can be just a step away.
