Sure it's fun to dress up, or dress up the kids, but to me pumpkins are the most evocative of this campiest of holidays. We grow huge and interesting pumpkins here (well, pumpkins grow well many places) and display them with pride.
Except for the obese-looking pumpkin pictured below that was part of a contest for the biggest pumpkin, the other shots here were what I call "random acts of pumpkins": Pumpkins carved or decorated and placed in public places, sorta like a Halloween version of yarn bombing.
While torrential downpours here west of the Cascade have brought down many autumn leaves, pumpkins still glow with autumn orange.
Pumpkin pie anyone?
