I've lost how many multitool pocket knives in my bags when travelling because I forgot I had it, even when I check my bags one ends up being discovered in some nook or cranny in a bag.

I have a hard time thinking I wouldn't be constantly mindful of the fact I had a gun on me, and would never pack one in a bag, but I'm not everybody and I have never carried everyday. There are parts of rural America and some cities where it is done as part of their every day carry and no one blinks an eye. So I could see it happening.
