I walk to work most every day. It’s like a 40 minute walk and I always take the same route. What that forces me to do is notice every little thing. Each day I see something new. Of course I can’t help but notice the cracked sidewalks as I trip over them or you know, on a good day, see someone else trip. I read about this idea the other day, taking old tires and turning them into a material suitable for sidewalks. It seems brilliant and perfect. Good design for a big problem. What do you think?
