Marion Tripp was what you might call a quintessential “Yankee.” From impeccable pie crusts to crackshot deer hunting, she regularly impressed people with her wide range of skills. When her daughter and son-in-law started an organic farm in rural Maine, she’d bundle up in a snowmobile suit and sell their rutabagas at the local farmer’s market.

They can’t navigate well or negotiate well in their environment.” Continue reading
