Wrong-O. We fly the Lone Star at the same height as the Stars and Stripes. It was written into the agreement that made the Republic of Texas a US state.
Basil, I'll asked you to provide a link to that agreement, especially where the flag part is written. It isn't there. Secondly all states fly their flag at the same height as the US flag when flown on poles side by side. If it's flown on the same pole then the US flag is flown on top. And there is nothing in the US Flag Code regarding Texas having any right nor in the Texas Flag Code....
Any links you can provide would be helpful.
