I purchased a ton of the stuff one year when living in TX.
It was for the coastal bermuda I was trying to grow.
Usually it is purchased in a hopper trailer and hauled away
by the buyer. After spreading the hopper is returned.
No one asked me for ID. They did want to be paid though ;-)
We used to get it by the pickup truck load in bags ,as our fields were small and there was a rental fee for the bulk wagon.circa 1970.
