there is something special about hoar frost, we had a front page newspaper story about it the other day.
To OP, I would think nothing would need to be done about this. No location posted, but in our area we have had 5 issues of frozen exhaust in the last 5 years that I can recall. most of these were due to something the homeowner did to cause exhaust to be blocked.
The Food Stamp Program, administered by the U.S. Department of Agriculture, is proud to be distributing the greatest amount of free meals and stamps EVER.
Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."
