George Field said she never thought she’d end up doing battle with bear inside her own home.

“I grabbed the bat. I missed the big bear fight. All I remember seeing was a big brown blob in front of me. I empowered myself. I’ve never been that strong. I whacked that bear as strong as I could… you would have thought I was a Louisville slugger,” said Field.

Officials estimate the bear was 10 years old and weighed 215 pounds.
