Two cows escaped from a trailer onto a busy Massachusetts highway, but a cowboy stuck in the traffic jam has came to the rescue.

In December, State police say a man wearing a Western hat and boots lassoed the 500-pound heifers one frosty morning as they wandered on Interstate 91 South in Springfield, one of the state's biggest cities.

Troopers shut down the highway for about 30 minutes as the man helped load the animals back into a trailer that was carrying them to nearby Enfield, Conn.

The cows had escaped into slow-moving traffic after a latch on the trailer opened.

Police say the cowboy hero didn't want to be publicly identified.
