In this photo taken Feb. 14, 2013, Samantha Goldberger, left, who had just set her camera on a timer, is surprised by her boyfriend Jason Skipton, as he proposes marriage, at the El Capulin reserve, near Zitacuaro, Mexico. Skipton found the love of his life 2,000 miles from home in a chance encounter that gave him butterflies. So of course, he said, there could be no better place to propose marriage than in a swirl of orange and black butterflies that had migrated thousands of miles to mate, at the monarch butterfly sanctuary in central Mexico.
