 problem that you did before. There's going to be a gap that goes from the soil down below all the way to the surface, and you'll get weeds and stuff growing up through there. So it's just a material that is difficult to work with. It's hard to make it look nice. And you have to pay a lot of attention to the environment, keeping people off, pets off, leaves and stuff from blowing into it when it's wet. You know, just a lot of headaches that you don't have when you can just press something in there.
