In Indiana, Fair Oaks Dairy Farm does more than just produce milk — it is also in the transportation business. The farm owns 60 trucks, which deliver milk to a processor halfway across the state. Last September, most of the trucks were converted to natural gas.
And in Michigan, there's a fight going on over one delegate to the Republican National Convention. Rick Santorum's campaign team says its candidate is a victim of, quote, thuggery. They accuse Michigan Republican leaders of engineering an after-the-fact rules change to give Mitt Romney a slim lead in delegates from last Tuesday's state primary.
We have more from Michigan Public Radio's Rick Pluta.

Greece has taken almost all the action needed to secure a second bailout from eurozone countries, according to the head of the European currency group.

When Grant Coursey was a toddler, he was diagnosed with neuroblastoma, a cancer often found in young children. A tumor had wrapped itself around Grant's spinal cord and had grown so that it pushed against his lungs.
Now 12, Grant is cancer-free; he received his first "clean" scan 10 years ago in March 2002. He had to undergo several procedures to rid his body of the cancer.
Recently, Grant and his mother, Jennifer, sat down to talk about his young life and how cancer has affected it.
Over the course of more than 20 years, Richard Diebenkorn created 145 paintings for his Ocean Park series. Nearly 80 of those works created between 1967 and 1988 are on display at the Orange County Museum of Art in Southern California. Diebenkorn, pictured above in 1982, died in 1993.
Diebenkorn played music in his studio while he painted — he loved Bach and Mozart — and it's reflected in his composition of colors. "I really do see them as kind of music," says curator Sarah Bancroft. Above, Diebenkorn's 1984 work, Untitled #26 — gouache, acrylic and crayon on joined paper.
In the late 1960s, while America was in turmoil over the Vietnam War and the assassinations of Martin Luther King Jr. and Robert Kennedy, a painter in Santa Monica, Calif., was creating a series of tranquil, glowing canvases that made his reputation and transfixed art lovers.

A Malaysian customs official examines elephant tusks at a port in Kalang. Malaysia has become an ivory transit hub, with African elephant tusks bound for China. Worldwide, authorities seized more than 5,000 smuggled tusks.
Armed with tips from animal welfare activists, I recently went on an ivory hunt with my Chinese assistant, Yang, in an antiques market in Beijing.
Activists say China's growing purchasing power is driving global demand for products from vulnerable animals, everything from elephant ivory to rhino horn.
Two huge stone lions stood sentinel outside the four-story market nestled among a forest of buildings off one of Beijing's beltways. In China, vendors usually accost shoppers and try to lure them into stores.
