I walked three hours in honor of my mother, who lost her right to walk when the roads without sidewalks became too wide, yet, today, she continues walking, contesting having more choices and modes of transportation.  Walking is the simplest and most sustainable form of moving, yet our society continues promoting private forms of transportation that take over our public spaces and transform our right to walk as a privilege of cities with good infrastructure and manicured parks. I do believe in walking and I advocate for walkable cities.
