I haven't smoked in a while and I wanna smoke ribs at my mother in laws tomorrow but I'm afraid if I start at 12/1ish and be done by 5pm ish the ash from the charcoal won't cool down in time by the time I leave her house later that night and she is anal about stuff being hot still when their not outside and watching it.....any ideas or advice ? I miss smoking so bad and it's perfect to make two nice racks of ribs
