Arrowhead Pride, a fanblog for the Kansas City Chiefs, provides a vaguely intriguing item this afternoon that reveals running back and bad Twitterer Larry Johnson, cut from KC Monday and now a free agent, is in Dallas at this very moment. And how do they know this? "Larry Johnson's reported location on his Twitter page -- which is updated automatically via the GPS on a cell phone -- is Downtown Dallas, TX." Commenters' theories abound: a visit with Jerry Jones, maybe; or perchance a sit-down with Clark Hunt; or, ya know, maybe he went to Bush's speech at SMU. Kent Babb at the Kansas City Star tweets that he's got the answer, or something close to: "LJ's agent, Peter Schaffer, tells me that LJ's visit to Dallas is a 'coincidence' and was a 'social business' trip. Whatever that means."
