In his blog, Rowe marks Thanksgiving day by expressing his gratitude for the crew and the fans.

"Whether we were dangling from bridges, crawling through mines, swimming with sharks, castrating sheep, transplanting giant cacti, or slowly freezing to death on the Arctic Ocean, we usually made it out in one piece, and we always got what we needed," he says of the intrepid cameramen, producers, sound technicians, and others who braved hazardous conditions to film the show.

As for the fans, Rowe acknowledges the show wouldn't have existed without them.

"In truth, it was really you guys who programmed the show," he notes. "Long after I ran out of ideas for more jobs, it was your suggestions that kept us on the air."

It's unclear if Rowe will continue with his other Discovery Channel ventures -- "How Booze Built America," which aired this fall, and narrating "Deadliest Catch," which is currently filming for an April 2013 premiere.

Rowe has other irons in the fire -- like appearing in commercials for Ford, Lee Jeans, and Viva paper towels. Earlier this year, he guest starred alongside Tim Allen on the ABC sitcom "Last Man Standing."

They have also announced they are cancelling American Chopper.
