Welcome, Oregonfarmer! You're in for a treat!
There are regional tomato taste testings. NORCATT is your local group. I don't know if they're active, or maybe there's another event in your area. People do have regional tastings, though. Someone in your area ought to chime in with current information.
This is NORCATT's forum:

Others may be able to provide links to "how to" threads.
