For what it's worth, I sleep just fine in the open.
What are the odds, really?
If I happen to be the poor chap that gets eaten this year, well heck, I guess it's my time to go.
While I love owning and shooting guns as much as the next cowboy, large bore weapons just don't make it onto my gear lists.
A Smith and Wesson 686 (.357 mag, 8 inch barrel), holstered and loaded with 6 rounds = 3 pounds, 9.6 oz.
A Glock 19 (9mm) with a 10 round magazine = 1 pound 12.9 oz.
...so the Smith and Wesson weighs about as much as my pack, quilt, tarp and bivy.
The Glock is heavier than my shelter system and kitchen combined...but it is likely too small a caliber to effectively stop a large, maniacal bear.
So the Smith and Wesson wins...
...although many gun aficionados will argue over the effectiveness of a .357 mag against a large bear, likely favoring a .44 mag...I'm sure someone will then argue that you should carry no less than a .50, or it's all about shot placement, or amount of ammo...(If you think the Chaff here is ridiculous, try a gun forum!!!)
...but I digress.
If I'm going to carry over 3.5 pounds of extra weight...
IT WILL BE BEER and I will be mauled happy.
