shoveling and salting

As a bus rider, I have to walk from 35th & Wisconsin to my home and yesterday there were several properties that still hadn't cleared their sidewalk of snow.   With the temps we had the snow/rain has since turned to ice.     I also noticed that there are properties that only shovel a small path, most of them are from the house steps to the street.    With the pending snow that we will be getting today, it will cover the ice on  the sidewalks.    Making walking more dangerous.  

In 2007 I had fallen on black ice and cracked my knee cap, which required me to have surgery and kept me out of work for several weeks.  The knee is never going to be 100 percent again.  So please take the time to shovel the sidewalks and salt them when needed.   Thank you.
