TULSA, Okla. (AP) — As family farms sell out to corporations and more farmers move to the city, it’s getting harder for single people in rural areas to find mates. Some are improving their chances with the help of a three-decade old social organization, Singles in Agriculture, that specializes in people like them. The group has members in 16 states, most in the Midwest and West. Unattached farmers, both men and women, get together several times a year in rural communities for dances, bowling or just to talk about agriculture.
