The rice and buck burners have small ash as one might assume, but Pea is usually full of clinkers of larger sizes. It will crunch up easily, and if your driveway is ice covered, then it works fine. One fall on a knee, hip, shoulder or your head will make the use for traction a question you will never ask again. Glare ice with a quick application of ash makes it walkable....safely. It does track to some degree, so if you want to buy ice melt or sand tubes to provide traction, go for it. It all relates to your lifestyle. This AINT Miami, so we do what we must to feel safe. I've used it for almost 50 years, and STILL have folks ask if they can get some for their driveways. I even now guys who add it to their sanders, and that method works wonders. The amount of salt and brine they use on our roads makes thinking about ash corrosion of vehicles a joke. They started today at 2 PM with brine, and the snow has been heavy since 4 pm. Slushy underneath, and the slushy crap is the damned brine working its magic (not my word for it) Sheet metal, fuel lines, brake lines, frames, exhausts, brake calipers....not a friend of any motor vehicle!!
