2 nights in a row, upon loading for the night on good bed of coals, intake the dogs out and a smoke cloud has gripped the street. Acrid, low hanging smoke. After about 10 minutes, it dissipates. Cause for concern. Yesterday neighbor was outside placing a precautionary call to the fire dept?! In the morning, normal burn down remnants and no smoke in the house overnight. I am getting new siding currently if that triggers anything for anyone? I'm all ears.
