Ok so we (People of Aurora) had a day off Tuesday for Jr's ACT tests and me and my cousin went downtown. There is this little piece of art between 16th and 17th and people use it to climb and parquer. I noticed how he used his shoes to climb up the walls easier.This put into my mind how the littlest advancement, like a shoe can help us survive. When i went over this several times i realized that it was more just the front of the shoe and the person's lower body strength. On the way back we took the lightrail. I noticed that the light rail would weave through the streets and back into a walled area. How do you think the walled area allowed it to operate more safely and how could they improve the system to make it more 21st centurith?
