Remember "Rootabigga"? I think this root is actually bigger. Mom and Dad have a great garden on a spot where they used to feed cattle. That fertile soil combined with the non-stop rain this year produced some sensational parsnips (and carrots, and beets, and lettuce that kept producing all season instead of bolting in July).
The boy is definitely bigger. In about a year he went from shortest in the family to tallest. I don't think there was anything special about growing conditions that year; it was simply time to grow.
