There is a non-profit group composed of citizens from Lake, Porter, and LaPorte counties that actively advocates building more trails and trail connections in NW Indiana called C4, Calumet Citizens for Connecting Communities. Their web site is
http://www.cc4cc.org. They monitor and report Marquette Greenway (that's what it's called, not the Lakefront Greenway Plan) developments amongst others. C4 also advocates for making NW Indiana more bicycle and pedestrian friendly. They meet once per month at the NIRPC office in Porter County. Details are on the web site. C4 members are actively engaged in things like letter writing campaigns to secure funding for trails, attending town council, planning commission, and park commission meetings in support of trails, trail clean-up, map making, etc. Join C4 and help make the change you want to see!
