In three weeks I'm headin' south, to the Deep South. I'm headin' to the Crossroads - the junction of Highway 61 and Highway 49 near Clarksdale, Mississippi. It's a famous place. It's so famous that the journey must be chronicled with TWO Dartoid's World columns. The next will show up in this space on October 1. Beware. If you've heard of Robert Johnson you'll know of whom (and where) I speak. If you haven't heard of Robert Johnson, you're about to learn why I'm so excited to make this trip.
