The dating scene in Center, Colo., a town of about 2,000 residents, is said to be pretty sparse. So when a local potato and barley farmer named Brandon Rogers decided he was ready to get hitched, he chose an option many young hopefuls do these days: reality TV. Rogers was one of four cowboy hat-wearing men courting potential mates on season two of FOX’s “Farmer Wants a Wife.” Like so many reality dating shows, the premise centers on single men in search of a woman to spend forever with.
