From her Wiki:
She briefly worked as a sports reporter for local Anchorage television stations while also working as a commercial fisherman with her husband, Todd, her high school sweetheart. One summer when she was working on Todd’s fishing boat, the boat collided with a tender while she was holding onto the railing; Palin broke several fingers.[5
For anyone who’s watched “Deadliest Catch,” yes, she’s tough enough.
UPDATE: NBC is confirming Palin.
