U.S. Rep Steve Southerland grins after winning an auctioned possum during the Wausau Possum Festival on Saturday, August 2, 2014, in Wausau, Fla. What is usually a must-attend event for statewide candidates was notably lacking of them this year, perhaps because candidates who now raise tens of millions of dollars focus more on television ads than making personal contact. But not attending is a missed opportunity, said Susan MacManus, a University of South Florida political science professor who drove more than 350 miles for the festival.

The sun begins to set as Alexander Schulz crosses the line, on November 25, 2014, Yangshuo, China. A daredevil has smashed the world record for longest distance walked on a highline - tiptoeing a massive 375m. The drawn-out line, which was anchored between two limestone boulders at 100m above the ground, beat the previous record by 70 metres. Alexander Schulz, 23, from Germany, spent three days trying to cross the line - falling scores of times - while battling ferocious wind and rain. Alex and his co-workers from One Inch Dreams, a slacklining company, set up the line in Yangshuo, China, where towering rocks covered in jungle foliage inspired the filmmakers of science-fiction epic Avatar.
