I used to walk this street, and not anymore since this little homeless encampment has been set up. I hope the city can find a better solution than allowing homeless encampments. I would like to be able to walk around my neighborhood and enjoy my neighborhood without homeless encampments. Also, this particular mattress has been lying in the middle of the sidewalk, really making it unattractive to pass by. Thank you for removing this mattress
