Agree .....
Flew continental and northwest this past weekend from Nashville into Colorado Springs. We carried on two rigs, one in a suitcase and one in a backpack. Absolutely no problems in Nashville. Upon our return flight, I did see a questionable face when it was scanned, however we were already the lucky ones to be chosen by our friends with the FAA. Obviously our rigs were discovered. With quick search expressing no concern and a pleasant, 'have a good flight' we were on our way.
don't worry, be polite, and have a good trip
