In my area, they sell it by the yard. I have no idea how that relates to tons. With the flooding rains, I'm going to need quite a lot.
Dave,
I am used to "by the yard" measurments as well. They sell dirt here by the yard. With stone, they weigh it and tell me a ton is roughly a yard. I'm thinking that is a BIG "roughly" depending on size and type of stone.
