I think I read that the big danger is when the turkey is still partially frozen... has to be completely thawed or there is risk of explosion. But 15 out of 2 million sounds like pretty good odds....
So this could also be a fun little activity for the Fourth of July...
Yeppers,
Here in town we have at least one house a year that goes up in smoke due to a turkey frier fracas.
Last year, a co-worker started frying his turkey at 6am. Next to his vinyl sided house (under a carport). At 7:00am he decided he needed to run to the store for something.
Did I mention it was windy?
At 7:30am he returned to a melted mess on the side of his house about to catch fire and on the other side of the wall his kids were sleeping.
~~sigh~~ Some folks should just buy their turkeys already cooked.
