CHEYENNE, Wyo. — Two men drove around at least two road-closed signs due to faulty navigation device information while trying to get to Yellowstone National Park and had to be rescued from deep snow, sheriff’s officers in Wyoming said Thursday.

Park County authorities said 60-year-old John Ray Elmore Jr. of Los Angeles and his father, 85-year-old John M. Elmore Sr. of Nashville, Indiana, likely won’t be cited for using the road northwest of Cody.

The road has been closed and unplowed since fall. Snow still covers much of the route, but the men said their navigation device showed it was open.

Their Nissan SUV got stuck Tuesday about a mile from the last road-closed sign. The men called for help on a cellphone.

Rescuers got them out with help from a resident with a pickup truck.

Many roads in and around Yellowstone National Park remain covered with snow and unpassable. In Wyoming, driving around a road-closed sign is a big no-no, possibly punishable by a $420 fine.
