Pumpkin might be short this year because of the dry July & August in Illinois. Spring was a bunch wetter than normal, but then rains mostly quit. About 90% of the world’s canned pumpkin (actually a brownish squash) comes from Morton, Illinois (Caterpillar City). The number of trucks to the processing plant on the highway and the number unloading seemed to be less than normal this year when we visited the grandkids & family in September, but they were cooking pumpkin. This was about 2 weeks ago, so it might not be in your store yet.
I have gone to every grocery store in our area for the past five days looking for Libbys canned pumpkin and found one small can in a Food Lion just today. Went to a Publix and bought the last five small cans. The stock guy said they just put two cases out about two hour earlier and my five were the last.
The Libbys website is blaming it on an unusually hot summer then added due to global warming. So I figure when there are no PPies at Thanksgiving, Trump will be blamed.
