Hubby usually does it before going to work at least the walkway/steps and a walking path width to the road. Most of my parents actually park at the bottom of the driveway and walk their kids up to the door so a path is enough. We use the sand/salt mixture so it is more to put a gritty path down than anything else.
We have been lucky since we have done it enough and get the daytime sun on the driveway that has kept it mostly clear a good part of the year.
