Could be a long-ago brain fart on my part but I noticed that US 41 north of Copper Harbor has an endpoint of ManRd_N, whereas I had put in the point before that of FortWilSP. The ManRd_N point is the location of the end of 41 and the classic big sign.
I'm just noting this in case someone else has gone to the end of US 41 and needs to change their log.
