Living dangerously - airport knitting

Decisions, decisions...

I will be logging quite a few airport hours in the coming week. I'd like to pack some knitting to keep myself occupied, but airline security has me worried.

I am only traveling domestically, so it is only TSA regulations that I have to contend with. The only problem is that even though TSA says knitting is A-OK, the individual screeners are allowed to make up their own minds. So it is still a bit of a gamble.

Option 1: I could pack the basket weave afghan that I have been working on forever.
Pros: It is on size 11 circular needles - very blunt and innocent looking tips.
Cons: It takes up quite a bit of carry-on space and is heavier/hotter than our other project options.

Option 2: I could start another pair of baby booties.
Pros: I haven't even cast on yet, so I don't have to worry about losing my work. They require only a little bit of yarn so they are space/weight conscious. As I mentioned before, everyone I know just had a baby, is about to have a baby or wants a baby - they would come in handy.
Cons: They are knit on size 3 straight needles. Pretty sharp and pointy looking. Plus, since they are so small, I am more likely to need a needle or scissors or other high risk items to finish them while at the airport.

Option 3: I could start a Branching Out scarf.
Pros: I haven't bought yarn for this yet, so I would get to visit the nice ladies at Carma Needlecraft, and I could get some bamboo needles (or chance it with the 8's I already have - they aren't too pointy).
Cons: egad! lace = scary.

I think I'm leaning towards option 2 or 3. It will most likely come down to whether or not I get my house cleaned up and bags packed in time to go yarn shopping.

On the subject of new projects, have you seen the summer Knitty yet? This is the greatest thing I have ever seen. Maybe for my next trip...
