i think it is more broken down than mulch but i am not the expert, anyway, it is down memorial just before 285 across from the prision. it is in the county building where you get your tags. there is a sign that says free compost or something with an arrow on the way into the parking lot. you follow that arrow. brings you into a large chainlinked fenced in area with a large pile of black stuff in the center that is it. i didn't feel comfortable there alone so if you are the sort to get uncomfortable do as i do and bring a pal.
