I have 5 bags of all purpose sand for a 4X8 dirt run. I know I might need to buy more, but it's a start. It hasn't rained since Sunday, it's been nice and sunny so the ground is dry. There's a few holes in the dirt; should I try to flatten it out first before spreading the sand or is it pointless? I am going to wait one more day since it's not supposed to rain again until Friday. Should I put some DE down to dry it out even more? Thanks for any suggestions!
