Okay another arena question - any recommendations on dressage arena borders? I am looking for a white, low rail to put around the edge of my arena and would consider a DIY project or purchasing an arena package. I don't want a chain - I want something a bit more sturdy and preferably something that I can move around if needed but is stable enough to not blow over in the wind. Any recommendations or companies to stay away from? Or any good DIY suggestions?
