The Kentucky Derby's 139th running is this weekend, and it will feature a sight that's been a rarity in the race for much of the past century — an African-American jockey.
"Everything that comes with the Derby right now for me is not the same as the majority of the other riders, or any other riders, because I'm the only African-American rider in the race," Kevin Krigger says.
Krigger was born in the U.S. Virgin Islands, but he's been racing in California. He's the first African-American jockey to ride in the Derby in more than a decade.
It's a captivating story: A global rice-growing revolution that started with a Jesuit priest in Madagascar, far from any recognized center of agricultural innovation. Every so often, it surfaces in the popular media — most recently in The Guardian, which earlier this year described farmers in one corner of India hauling in gigantic rice harvests without resorting to pesticides or genetic modification.
