Beefsteak in WA? I guess I have no idea what the weather is like on the NE side. I'm right on the coast: like 1.5 muiles from Posession Sound. Warm winter, cool summer. Cloudy 8-9 months per year. Drizzle or rain 5+ days per week 8 months per year.
Your microbadge and Zone imply "cold winter". I hope that means you have enough warmth for mid-season tomatoes.
Last year was my first year ever for tomatoes. I didn't even start from seed, but 2 of 3 varieties surprised me by ripening. For months, all I had were green golf balls and marbles.
