I agree with all of the reasoning above, but I still only carry one firearm, except when carrying a back-up while hunting in grizzly country in Alaska. I just got back from a month in Africa (I was not hunting) and my entire luggage for the month was 1 carry-on weighing just 16 lbs. The same with a month spent in the jungles of Papua New Guinea last year. 1 bag weighing 16 lbs. I get a challenge out of doing the most with the least, but that's just me, I'm a little ... different.

Beware the man who shoots only one gun ...
