Some American Bison taking a midday cool-down at a pond of water in their field at Shelby Farms here in Memphis Tennessee. Shelby Farms is the largest urban park in the United States. At 4,500 acres, it's over five times the size of Central Park in New York! The herd recently mixed in with another newly arrived herd, giving the group some much needed new blood. These days they are extremely healthy, and several newborn have joined the group this year. One is pictured here. Hard to imaging their herds used to be the size of a large state, and equally difficult to comprehend how they were ruthlessly slaughtered almost to the point of extinction. It boggles the mind. But their numbers are growing once again thanks to good people like the ones over at Shelby Farms. Thanks for viewing, marshall
