DUNCANSVILLE, Pa. (AP) — Police say a Pennsylvania man picked up more than he bargained for at a yard sale.Duncansville police Chief James Ott tells the Altoona Mirror (http://bit.ly/nZzJzs) that a small snake bit Donald Forshey on the leg Wednesday as he and his girlfriend were driving home from a yard sale.Ott says the snake likely slithered into a milk crate containing items the couple had purchased.The pair bailed out of the car on Interstate 99 and called 911. A state trooper was unable to help them find the snake, which Forshey tried to pin to the floor with a crutch he uses.An ambulance was called as a precaution, but Forshey is OK.Authorities believe it was either a garter snake or a copperhead that didn't inject any venom when it struck._ Information from: Altoona Mirror, http://www.altoonamirror.com
