In individual bowls, divide in this order: the lettuce, tomatoes, blue cheese, bay shrimp, vinegar and oil. Serve.
Notes
Winter for some reason makes me want a crunchy salad. There are a lot of lettuce snobs out there, but not me; I want iceberg lettuce. If you can't make yourself use the lowly iceberg lettuce, use romaine as it is crunchy, too.
