re: Do you have a favorite Hemingway biography?

Try Ernest Hemingway in the Yellowstone High Country by Chris Warren. Spent a night in Cooke City MT during a Yellowstone trip, visited Miners Saloon and the bartender had a copy behind the bar. Started talking to him, turned out it was Chris, the author, who grew up in Cooke City and was familiar with folks who hung out with Hemingway. I had to buy the book from him (autographed, of course); excellent read and I’m not really a Hemingway fan.
