On e-bay Blue Ribbon lists the source of Ky Cabin as Gary Millwood who got the seeds at a tomato tasting. Seeds were sold in stall at a market by Megan & Todd Childers. Those seeds were from a friend - big yellow tomatoes grown in eastern Kentucky for years. Blue Ribbon said hers were under a pound but someone claimed to get big tomatoes. similar to Buckeye Yellow also a Kentucky tomato. Go to Blue Ribbon and read it for yourself and you can order seeds because it sounds like the same tomato.
Evidently
not if I had read Jimmy Cracked Corn's blog carefully which clearly says his Cabin is dark pink and 4 oz.
