Trace Adkins and Toby Keith are on the road together on a trek dubbed "America's Toughest Tour." Adkins says he thinks it's a good pairing, and notes he absolutely stands up to the tour's title. But Adkins won't speculate on who's tougher, and gives Keith credit for holding his own. He adds that he's not interested in challenging his tour mate, admitting he, quote, "wouldn't want to find out which one of us was the toughest, and I hope he won't either." The singers will be spending the weekend in Florida. They have shows in Tampa on Friday, West Palm Beach on Saturday, and Jacksonville on Sunday.
