I'm planning to attend some demonstration these coming days. However, winter is upon us, and there's going to be rain. And the placards are made of paper; thick paper board, but still paper, which will not withstand anything more than a light drizzle.
Now, you must be thinking: "Use a large umbrella". But the thing is, I need both hands to hold my placard. (Plus, an umbrella is rather unwieldy, and makes you a more attractive target to opponents of the demonstration.)
So, what would you recommend as a solution for keeping my demonstration placards(s) dry and visible?
Notes:
- If you suggest using a different material, note that poster longevity is generally low because the police often tears them up or confiscates them. Also, assume there is currently a set of posters that I need to work with and they're paper.
- The location is Israel/Palestine, and the temperature is low, but markedly above zero.
