One of the hottest meme Facebook groups right now is about...trains. Yes, trains. New Urbanist Memes for Transit Oriented Teens has over 200,000 members, and posts range from comics to pictures of high-speed trains to discourse over the importance of bike lanes. Issues around transit and urban spaces hardly make it to the national debate topic list, but on the internet, they're center stage. Why do young people care, and how is city planning changing under their influence?
