A dry county is a region of the country that has voted together to enforce prohibition on the county level. Reasons given for having such a county-wide law include: elimination of drunk driving, community health, and one less cause of moral dissolution. Since prohibition is forbidden on the national and state level by the Twenty-First Amendment, this is the best that prohibitionists can currently attain through legal channels. Kansas and Arkansas are among the states with the most dry counties. The opposite of a dry county is a "wet county".
As of 2012, there are more than 200 completely or nearly completely dry counties in the United States - nearly 10% of all the counties in the nation. In addition, there are many "moist" counties that also place restrictions on the sale of alcohol.
