It didn't have to but I wanted to get it done yesterday since it's supposed to be cooler today and I need to mow and put down fertilizer. The dirt in the front of our house has really sunk over the years and I'm trying to get it built back up and sloped away from the house. I am going to grab 10-15 bags at a time to fill it in. I was going to have dirt hauled in but decided I didn't want to do all that shoveling.
