Or, even better, hide a water ballon filled with deep red water in the head of the snowman, so when somebody kicks it like the little immature idiot they are, they will be suitably shocked...

but like you said it LOWERS the freezing temp, not makes it immune to freezing. Completely saturated salt water still freezes at -6 degrees fahrenheit (like -21c). Most people probably wouldn't saturate it completely with salt so its more likely to be higher than that. Plenty of places get much colder than even the -6F.

It lowers the freezing temperature...
