For Halloween, my grocery store was selling little bags of decorative squash. After Halloween, the decorative squash went on sale (and with good reason — some of it had started to get moldy, which was disgusting). In addition to the (non-edible) decorative squash, I got a couple dumpling squashes and a carnival squash, which will hopefully become squash soup sometime in the near future. IMO, the edible squashes are prettier than the decorative ones (but the decorative ones do make nice filler).
As usual, more pix on flickr.
