Weather is predicting a fair snow fall on Monday, so I will be able to test the sweeper, and the larger heater when that is finished. I used the chimney as a quick and dirty place to attach the big rope. While this will not allow the full test of concept, it will give me some real world experience. Last week I wanted the snow to stop, now I can't wait for it to snow again,fickle human that I am.
The snow missed us completely, so no test was possible. Will leave things set up, and hope for at least one more snowfall before spring.
