Just let me know your US mailing address. I will get a flag, have it run up the pole here, (usually about 5 minutes), and the Army will create a certificate of authenticity, with the date, and signed by the commander. Then I mail it to your lodge. The cost of the flag is about $17, plus postage. Delighted to do this for you.
Once you get the flag, it is yours to do with as you wish. Most lodges do not expose the flag, to the weather. Some get a display case to hold the flag. One lodge in Mass, has the flag on their altar.
