A PBS documentary called Rails to trails will begin airing online beginning Wednesday.  It will first air on TV on PBS Wisconsin channel Sunday at 8pm.  The documentary will feature the Elroy-Sparta bike trail and be narrated by well-known actor Edward Norton. First started in 1967 abandoned railroad tracks were converted to a bike trail between Elroy and Sparta, the bike trail would grow as more tracks were abandoned. The example set in our area helped lead to more tracks to trails start up across the country.  Elroy native and former Governor Tommy Thompson will be a guest on the documentary.
