Call the VFW or American Legion about the flag needing disposal, and visit the local meeting hall to deliver it (yes, that bar/saloon you have been avoiding all your life). I don't know if you have ever thought about the welcome you might receive visiting a VFW hall, but it may surprise you. The people who frequent the Hall may be worth your attention.
I too never visited a VFW hall in my younger days (except for a wedding and a few community meetings when I lived in a very small town) because I am not a Veteran. When I was old enough to legally drink, the anti-Vietnam stigma was strong enough to discourage a visit (that and the threat of getting my ass kicked
from some mean hombre "Eagle" character, for being ignorant about war).
When I traveled overseas, however, (specifically in South Africa, Australia and New Zealand), I found the various Veterans meeting halls are popular places in the community and usually granted special sales permits (alcohol sales, I'll admit what I was looking for). This liberal sales policy made these places a common community forum for local affairs (and a great place to have a drink). I seldom found a contrary anti-American soul in these halls. I never found anyone who judged me inferior for not participating in active Armed Service. The experience was quite different from the popular culture reputation these organizations receive here in the USA.
When I returned home I found the same warm attitude, and welcome, visiting the VFW hall in my old desert hometown (the same place I avoided except for the wedding and meetings).
Hindsight makes experience easy, and when I was very young the VFW and American Legion membership were always visible in the community, and this visible community participation dropped off after the Vietnam war (in my community). I have learned to believe these meeting halls were unfairly avoided after the Vietnam conflict, and unfairly lost much of their valuable positive influence on the community (in contrast to the healthy influence these halls have on community life in other countries). I don't know if stigmatizing the VFW was an intended result of the anti-Vietnam activist agenda, but the protestors succeeded in discounting a major positive community influence (along with the resource of experience within the VFW and American Legion).
It is troubling (to me) to realize that it took viewing my country's culture from half way around the world, from countries with no anti-Vietnam cultural baggage, to understand how popular culture unfairly minimized the influence of Veterans in our community since Vietnam (and organizations like the VFW). These folks will help you care for your flag, but they will also help you care for the community.
