When I was an EMT I carried an large, well stocked BLS bag. These days I keep a simple kit in a black camera case similar to the one you described. It's just a small trama kit I can keep with me for gun shot wounds or other situations. I am looking toward upgrading some of the items based on what I've read in the Zombie Squad first-aid subforum. Lack of money has held me back from those upgrades. I'll have my kit with me in the car at the meeting Wednesday. I'll show it to you then.
