Hey, I just wanted to clarify a statement I made, in particular the
first one. I stand by it, but put it in the context that stray
bullets falling rarely hit anybody. Of those that do come down,
large caliber rounds certainly can cause trauma, but even then usually
not enough to cause death. The statistical blip mentioned in the
Wikipedia article probably has some merit, just not enough for me to
worry about. The smaller caliber rounds (pronounced "lighter" or
"less massive") that we would typically see in the USA are of
extremely low concern when compared to the larger .30 or .50 cal rifle
rounds you might see elsewhere during celebrations. I'm certainly not
saying it doesn't happen, I'm saying it's rare. Focus on eating less
cheeseburgers or wearing seat belts more often if you want to save
As for me, I will be driving to the target range today while wearing a
seat belt, shooting my .308 in the cold, and won't be eating a burger
-but I had one yesterday!

The Wikipedia article has an interesting statistic... bullets falling from the sky are 5-15 times as likely to be fatal as direct gunshot wounds. A couple of articles to start with:
