No big deal, I like to poke Greg once in a while and he me. The CW changed the usage of National flags in many ways. Most northern State didn’t have a political State flag until the trend was started by the southern States. The U. S. National flag was seldom seen outside of a military post or Washington D. C., the use of the Stars & Stripes by schools, the Post Office and Government building started during the war.

Happy Trails!
