REDDING, Calif. -

A retired fish and game warden from Redding has become an author and is using more than 30 years of experience as material for his first book.

Steve Callan's book, Badges, Bears and Eagles, is getting positive reviews from critics.

It highlights the more eccentric "on-the-job" experience of being a game warden in the organization, now called Fish and Wildlife.

A signing at Costco Friday had all the books sold out within two hours.

Sales have gone so well that Callan's publisher is even talking about the possibility of a second book.
