Keep your letter short, focused, and interesting. In general, letters should be under 200 words, 150 or less is best; stay focused on one (or, at the most, two) main point(s); and get to the main point in the first two sentences. If possible include interesting facts, relevant personal experience, and any local connections to the issue.
