Do you feel Lucky? Highway 13 was called Lucky 13 in the past, and some people in the area still refer to it as that.
State Highway 13 starts in Wisconsin Dells (exit 87) and runs up to Lake Superior. It follows the lake's shoreline from Ashland to the city of Superior itself. The road goes through communities such as Adams-Friendship, Wisconsin Rapids, Marshfield, Medford, Phillips, Park Falls, Mellen, and many others.
The cache location is a special intersection on Lucky 13 (check out the road signs). You can drive right up to this dead-end wannabe. Bring your own writing instrument, and try not to be too obvious when you are looking for the hiding spot.
