This gives me the strange urge to pack a pumpkin on my next flight, but my next flight is international so that's probably not a good idea. I don't think I can convince my wife to take a pumpkin on her domestic flight next week.
Somebody mentioned traveling with eggs, so I had to look up the volume of an egg. According to one site, an average egg had 1-3/4 oz inside it. (3/4 oz of yolk & 1 oz of white). That makes me want to travel with a carton of eggs. I was thinking about hard boiling some or all of them to have fun with the TSA if they try to confiscate them.
