Reducing plastic: Banners at General Assembly

I've been thinking about how to reduce my plastic use, if for no other reason than it doesn't biodegrade in a lifetime. (Crumbling isn't the same.)

Because the Unitarian Universalist Association General Assembly is coming up, I have to wonder again about the Banner Parade -- a major feature of the opening plenary session -- and the poles made of PVC pipe that banner carriers use in the parade.

Because they're cheap but unwieldy, I've been guilty of bringing a pole set and discarding it almost immediately, which is a waste. But PVC isn't a great product, and besides the pole sets dip and yaw unless they're glued (like plumbing) ahead of time.

I wrote about it two years ago, but have neither the need to come up with a solution -- but thanks to Dan Harper for chiming in -- or the engineering chops to makes something, I let it go. Does anyone have an idea now, if not for this GA then next? (And do I recall a suggestion that the banner parade might go "virtual"? Not a good idea, methinks.)

As for the banners themselves, I have an opinion there, too. Mainly that the best ones are graphic and easy to read from a distance. Past, but still useful, posts here and here.

Later. Oh, this is post #2400.
