Hi all. I live North of Winnipeg, and am building an outdoor riding arena. I have graded (to drain) and compatcted my base of clay and gravel. I'm looking at types of sand to put on top. The most popular I've found are septic sand or clay sand (less then 10% clay).
Your thoughts? I'm a barrel racer and do the odd pleasure / trail class.
What do you have? Does it work for you? Any suggestions or comments is much appreciated.
