I got pulled into secondary by tsa cause there was something in my carry on that was suspicious. Real serious dude asked me if I had anything to say. I was dumbfounded. He proceeded to open my carry on which happens to be my day pack I use when I actually hunt, searches...now my curiosity is piqued...I have no clue what it could be cause surely I checked every pocket before I packed a change of clothes in there for my 1 day "trip". Well, it was my sternum spreader that was in its case. He pulled it out, looked puzzled, I busted up laughing and told him what it was. He had a horrified look and said have a nice day.
Other than that, year old snickers is usually what I find in a pack...when I actually hunt.
