On this week's Second Look, WMRA's Christopher Clymer Kurtz tours an old home, soon to be a new museum -- it was built by former slaves in Harrisonburg in 1895... Calvin Pynn tracks the changes in Scouting, in evidence at a Scout tradition -- the pinewood derby... Peter Jump tags along with a doctor who may represent a return to the "house call" tradition... and, Jessie Knadler meets the wordsmiths behind the clever new electronic safety signs you've probably seen on the Interstate.
