In 2011 I learned the Utah flag I had seen my whole life was not the correct flag. I was amazed how pretty the correct one was. I voted to have the flag manufacturers start making the correct Utah flag. If you have a flag that was made between 1922 and 2011, you can still use it but look at a newer flag. Some want to change our current flag but have not seen or compared our current correct Utah flag.
