Halloween flash fiction contest -- front page of Lulu
I happened to note the Halloween Flash fiction contest on the front page as I came in. Open until 10/22. 1500 words or less, usual rules disclaimers, all that.
I'm in; thought it might be fun. If anyone else jumps in, post here so we can compare notes later.
