And your tripod didn't get groped by TSA :mrgreen:
Meh, I figure it's just as bad for them as it is for me. Also, I know it's controversial, the pat downs and all, but at least it's finally meaningful security. None of this worthless and illusory nickel and dime crap...."Oh hey, they can put bombs in shoes, so let's x-ray shoes" or "Oh hey, they can make bombs out of liquid, so let's restrict liquid". If they're gonna do it at all, they need to do it right, otherwise they're wasting everyone's time and money. Making dumb people feel safe and stopping terrorists are two completely different things.
I'm still waiting for them to realize that knitting needles can be just as lethal as box cutters.
Seriously:
TSA: Transporting Knitting Needles & Needlepoint
Getting back on topic:
TSA: Photographic Equipment & Film
No specific mention of tripods or monopods, so I think it's up to the whims of TSA personnel. That said, they do prohibit things like ski poles, hockey sticks, and other sporting goods.
FWIW, I just traveled (and do so somewhat regularly) with a poster tube (black, plastic, screw-on end cap, nylon webbing shoulder strap), which incidentally looks like it could contain a stinger missile. Nary a glance from TSA.
