(Centerville, IN)--They’re calling it a ghost bike, and if you travel U.S. 40 near Centerville, you may notice it. It’s been placed at the spot where Joanna Abernathy of Australia was killed two years ago. Joanna was riding cross-country to raise money for the Martin Luther King Foundation. This week, Wayne County Sheriff’s Deputy Kyle Weatherly joined Joanna’s friends and family at the site. For the next couple of weeks, a group will continue her ride to Washington and hope to get there on her birthday.
