Ever since QEII passed, I've noticed a lot of flags at half staff (or half mast for you Navy guys). I don't know of any American of prominence that just died so I suspect it is for the late Queen. Personally while I think she was a fine person who well represented the U.K., this is not the U.K. Why would we lower the flag for a foreigner, even a friendly one? Maybe all these lowered flags are for something else, and if so, I stand corrected.
