A second participant in a cross-country Harley-Davidson race has died -- this time in a crash on an Alaska highway. Alaska State Troopers say 63-year-old Kenneth J. Greene of Ocala, Fla., died after wrecking his motorcycle Sunday afternoon on the Glenn Highway near the Matanuska Glacier. Troopers say Greene had been participating in the Hoka Hey Challenge, an 8,300-mile motorcycle race starting in Key West, Fla., and ending in Homer, Alaska. http://sports.espn.go.com/rpm/racing/news/story?id=5356640
