Hello, this spring I am finally getting a riding arena! It has been the calving pen for the last few years but my grandparents have down sized and they only need the smaller one. This so call "arena" is a very oddly shaped paddock, its sort of a deformed hexagon and one length of it is a cover all tent. Its well fenced and has two large gates for tractors and one so I can bring calves in the work with.
As of right now the ground is fairly uneven so we are using a bobcat to level it come spring. The ground itself is thick clay that gets slippery when it rains. I am thinking I will need to mix it with some sort of rock? What sort of sand should I use and how much?
