When Medlen was still with JFR, every once in a while a JFR trailer would be near Dardanelle, (in Yell County for you True Grit fans) Arkansas along I-40.
I had a chance to talk to John at Epping last year and asked if he still visited that area of the state. He doesn't. But, his mother-in-law lives about 30 miles from I live and he goes there when able.
