LOL, I was just sweeping up the cedar chips from my entrance hall a little while ago that came in from the park with the boots and splashpants this morning. I see dogs using the cedar chips at the park all the time and my dckids sit and dig in them, eeeewwwww! What are you going to do? Squirrels, cats, raccoons, dogs, their pee is on everything everywhere. I just a germophobe, but I would stick with grass.
