I'm still sad about having so many scanners preventing things like pocketknives in public spaces though. I generally carry a pocketknife with me everywhere I go, and there have been a number of times where I just haven't even thought about the fact it's on me when I end up going to a sporting event. They're pretty useful things; I probably use mine a few times a day.

Luckily some venues are nice about checking it with security, but still a pain to have to remember to go back and pick it up when leaving.

Wouldn't it be nice of people would just quit shooting and stabbing each other at things like sporting events :(
