Depends on the idiot TSA screener. A few weeks ago, in LAS, I was stopped because they had to separately screen my portable CD drive. ok, so maybe that is considered a computer by some, even though it cannot operate on it's own, but why did I have to go BACK through the detector, re-remove my shoes, take it out of my bag and re-run everything again? 'cause there are stupid people out there. I carry that drive every week through LAS, and it has not since, nor prior, been checked. Forrest G's mama had it right.
