Here is my schema:

```sql
CREATE TABLE article_to_warehouse (
  article_id   INTEGER
, warehouse_id INTEGER
)
;

I often re-read The Legend of Sleepy Hollow around Halloween time. If you haven't read the original (published in 1819), it's a really fun read, with great descriptions of (obviously somewhat fictionalized) life in a town on the banks of the Hudson River in 1790.

What other short stories or books would you recommend for the Halloween season?
