I do a snow maze too. But I start it at first snow fall and go out daily to walk it. No snow blower (though that would make a wider path easier). I loop it all over the yard and have little areas off the path (little houses, just a semi circle of clearing).

It is totally worthwhile! It gives them a clearing to walk and burn energy and keeps them busy. They can be trains, buses, cars etc while running the paths.

Today was freezing rain. We brought out the side walk chalk. It is neat to draw on the wet pavement.
