With the recent winter storm and nasty blowing winds, please take the time to check your dryer and furnace vents. The wind may have blown the snow over the vents, preventing them from working properly. They could be on the side of the house or on the roof, for your furnace.
This could create some bad carbon monoxide levels that could be deadly. Here's a picture of my dryer vent that was plugged. A big THANKS to my alert neighbor, Thea, for letting me know. -Alan
