After talking to Sharon, it occurred to me that I should make an announcement. After the first feast, I saved some tomato and pepper seeds in hopes that they wouldn't vanish, and I could plant them. They didn't, and I did. After the most recent feast I, and some others, made an effort to save enough food for a couple of days. We probably should have said something after the first feast, but didn't. Frankly, I assumed everyone knew because some of us posted about it. But people may not have hung on my every word, as it turns out. Mea culpa.
So.
If there is another feast--and I hope that there will be--
everyone should come prepared to carry off some extra food. If you have any containers, especially ones that you can seal, bring them. Especially plastic ones (there may not be any, but plastic lasts a long time, so...there might be some tucked away somewhere on the island). Even without refrigeration some foods will keep for several days.
Also--among all the people here with powers: is there anyone who can create ice, or just make things cold? If so, perhaps we can establish a communal ice house or something similar.
