We stopped by Blacklick Metro Park for a walk and explored the connector trail heading south. The trail is paved and follows Blacklick Creek under I-70 and Tussing Road where it ends. From there riders will need to take Tussing to Hines Rd and follow the mix of trails and roads down to Three Creeks. MORPC map is here to see the southern routes. I may try this as a ride sometime in the near future.
