It's like driving a car in the snow. Not recommended unless you have to.
Seems like it's irresistible for a lot of people (me). I want to enjoy the winter flying, so I accept the challenge of the ice/snow. In a car or plane, approach it as if you have no brakes. Basically, it's inertia management. Making sure you have enough room (distance and width) to coast to a stop. Or ground loop to a stop (worse case on a smooth icy surface). Taking off and landing in snow is like having the brakes on. I imagine the amount of braking it would take to nose over on landing as the the friction produced by the snow. That's a LOT of braking in a KF in a 3 point configuration. And if you can take off in it, you can land in it. So, (if you MUST), have fun!
