BOS has them in Terminal A, at least in the elite/medallion/DL Shuttle line. It works great, and I cannot imagine it is expensive, though I often underestimate the government's ability to waste money.

I can think of two things that would be entertaining to do as part of this new effort:

• One would be finding a way to "tag" an undershirt with a material that would not set off a WTMD or HHMD but would show up on the millimeter wave bodyscan. Foget writing KHIAI on a mippie bag when you can wear it!
• The second would be to come up with some mock bios and swap them out. This one is more risky as chances of getting turned in are higher, and they probably can charge you with vandalism for doing so. But imagine how fun it would be to have alternate bios on display throughout the lines.

Let's get planning
