Standing back -- careful not to trip whilst doing so -- I think that the pink roots are more of an indicator of the sad state of the frivolous lawsuits that fill the courtrooms (and cost us all) In some ways, I believe that private property is more vulnerable to those lawsuits than say, a State Park. Case in point: the local mall used to allow walkers access before general business hours, however, one day, someone tripped over his shoelace and broke the arm.....and promptly sued the mall (now the Cinnabuns are a dollar more)(and groups are not allowed to walk at the mall before hours anymore) I am not sure that it would be so easy to sue a state park if one tripped, due to the long list of disclaimers that one encounters at the kiosk.
