Very sound advice. Lots of guys here will say you need 2 guns, infrared scopes and a pack of dogs...but its simply not true. Respect the bear, be smart, but don't be afraid. A pack alarm is a great early warning indicator, and most of the time will startle whatever trips it into bugging out, follow Srupps advice on things in your tent and you will be just fine. You don't need multiple guns, bear spray wouldn't hurt, but look at how many days and nights people are outdoors in Grizz country each year. Last year was an odd one, we had a few encounters, but generally speaking there is one or none that make the news. Theres a reason for that.
Also if you have a dog, if the dog gets mamma fired up and she chases it...I personally don't bring a dog. Ever seen that youtube video of the bears chasing the dogs and the guy is in his shed? Yeah, that didn't go well...
