Old Graffiti

Yesterday I saw some graffiti that is older than I. Older by a year (more or less). It was the good ole sidewalk-initials-graffiti. Complete with some so-and-so plus so-and-so. I found it a little odd that the sidewalk was over thirty years old. It was in very good shape considering. It made me think of defaced picnic tables and whatnot and how eventually they are replaced. Even putting ones name in "stone" doesn't make it last forever. Eventually sidewalks get replaced. I wonder if they get replaced more quickly these days. I don't think I've noticed a thirty-plus sidewalk before. Maybe they don't make sidewalks like they used to.......
