Medium Rare it's funny you mention what might be left in 20 or 30 years, when I was in college our coach told us that in 20 years there would only be 4 beef breeds left, while there are still numerous breeds left is less strength in 2 of the breeds he thought would dominate. He claimed that the 4 breeds would be Angus, Hereford, Limi and Maine. I look back at that comment and wonder what happened.
It's interesting watching the breeds cycle through the years, what's popular what's not and where the money gets spent.
