I've traveled all over USA with everything. The tighty whitey method is the best way. Or to put it simply, keep it hidden on your person.

Tough after toking a few quickies in the airport BR & your paranoid. Fun, fun, fun.. Big "BUT" though. You could be subject to a random strip search most likely in FL or somewhere near a border.
