Lots of folks use rice hulls for horse bedding - it's easier to work with than sand as it's much lighter weight and a bit more absorbent - LOL. It is a wonderful thing to have access to such a good option... for the price of a little manual labor. (Not too much... rice hulls are so fluffy and light weight!) I'm envious. I'd love to have something like that just sitting by the road. My shovel would take up permanent residence in my truck - right next to a large plastic container.
I will just have to hook up my little red trailer and tow it to the site. Its on the way to town so I can drop Bernie and his shovel off, then pick him up a few hours later.
Thanks for validating its use. I was at a bit of a quandary as to whether it would be ok.
