Hi Todd.
I have been reading your posts and thought that there was good advice on your tomato starts.
What I can add on the viability of seeds in the storage conditions I have for them is that it sure seems to be a good idea for me to renew tomato and pepper seed every 2 or 3 years.
Getting out around 5 years, delayed emergence puts the seedlings at a real disadvantage if they are competing with others when started in community containers. Old seed can be a problem in any circumstance. Failing to have any technique to my seed storage means that I just have to pay attention and set "pull dates."
The early varieties of warm-season vegetables have been important to me. The usual combination of Pacific Northwest spring weather and higher elevation night temperatures have been challenging.
Melons? Years ago, I found the University of New Hampshire's galia melon, Passport. After about 10 years of successful growing of that variety, the seed has become a little difficult to find. I followed Johnny's Seeds' advice and grew Diplomat, last year. With record high spring 2015 temperatures it was an excellent melon year and Diplomat performed just fine.
U of NH also put Goddess cantaloupe on the market. Great success with that one. I'm still searching for a charentais melon variety I can grow.
Sugar Baby watermelon has been disappointing. Yes, I tried Blacktail Mountain. One year, the seed failed to germinate. A couple years ago, on what should have been a good melon year, the vines failed to produce ripe fruit.
Shoot. I can very nearly see Idaho's Blacktail Mountain from my garden!
This year, I have little Yellow Doll plants to set out this week! DW is
suspicious of a yellow watermelon altho we enjoyed one from the farmers' market a couple of years ago. I have high hopes!
Your comment on Tiny Tim tomatoes: I have grown Kimberley tomatoes for several years. It is very early and comes from a British Columbia mountain community only a couple hundred miles from here. It is supposed to be a Siberia x Tiny Tim cross. Certainly, it isn't a miniature but, along with Bloody Butcher, will be the earliest ripe fruit from my tomato patch. The first miniatures I have
ever grown, Red Robin, are in 8" pots for this season ... just for fun.
Nearly all my 20+ tomato varieties are early choices. I find it disappointing to be standing in the garden, expecting that first frost by morning, and realize that only 1 or 2, or not a single, ripe fruits have come off of some of the vines.
Finally, welcome to the forums, Todd. Don't pay much attention to that north/south rivalry. Realize that we are from most everywhere and benefit from each other's experiences and learning how they differ
