As for the flag, if you want to fly country flags, a great place to find good quality flags of all countries in all sizes, often with a halyard mounting cord sewn in, is a marine shop. When I tour abroad, I always fly my country's flag. If I know it rubs on the locals for whatever reason, I replace it with a dayglo triangle, so as to not get nasty remarks or punches in the face.
I managed to find a standard orange triangle one and mounted it with....what else...hockey tape (I am Canadian, after all). I wouldn't mind flying my nations flag. It rarely illicits punches in the face or rubs locals the wrong way.
Of course, just today, some jerk putting his bike in the bike rack at work snapped my flag pole in half, but I fixed it with...what else...hockey tape!
