Whats a good dirt mix if your building an indoor dirt oval track ?

Only use left-handed clay.........

Clay. Some guys have built tracks using baseball diamond clay, but many times it contains too much sand (abrasive).

The best clay comes from the south, from the bottom of river beds, but many guys have said that the absolute best clay to find is that from really deep contruction digs for things like skyscrapers and very tall buildings.


And yes, dirtoval.com is a great pace to go for questions like this.
