Present TSA rules and enforcement can make for a headache as you go through security. Liquids and gels get a ton of scrutiny. My folks will bring me out some sausage and it always gets put in the checked baggage, nobody cares about the ice packs there and its always still frozen. The greater the frozen mass the better.
My worst case was when they scrutinized a small batch of golf balls I threw into my carry-on at the last minute. Two of them were a three-piece ball and looked different under the scanner than the others. Nothing like four agents each analyzing a golf ball as I wondered if I'd catch my flight.
