Last leg of the trip--Las Vegas to JFK, same setup, but this time traveling with wife and toddler, so we've got more stuff with us and one checked bag. No questions at security about the tripod. X-ray inspector asked if I've got some "heavy duty camera equipment" in the camera bag, but no more than that. The diaper bag got the full explosive swab test, because it had a sippy cup with some water in one of the side pockets.
