I recently got a round pen but we still haven't sand or anything under it so it is siting on red dirt(well its mud right now) and I was wondering what the best footing that is inexpensive is. Right now it is about 40 feet wide but we might add on to it later.
The reason I can't just use the red dirt is because when it rains it get really slick and in the summer when it is dry it gets really hard. I also wanted to know how thick the footing needs to be. Thanks!!
