<P> Since the 21st Amendment repealed nationwide prohibition in the United States, alcohol prohibition legislation has been left to the discretion of each state, but that authority is not absolute . States within the United States and other sovereign territories were once assumed to have the authority to regulate commerce with respect to alcohol traveling to, from, or through their jurisdictions . However, one state's ban on alcohol may not impede interstate commerce between states that permit it . The Supreme Court of the United States held in Granholm v. Heald that states do not have the power to regulate interstate shipments of alcoholic beverages . Therefore, it may be likely that municipal, county, or state legislation banning possession of alcoholic beverages by passengers of vehicles operating in interstate commerce (such as trains and interstate bus lines) would be unconstitutional if passengers on such vehicles were simply passing through the area . Following two 1972 raids on Amtrak trains in Kansas and Oklahoma, then dry states, the bars on trains passing through the two states closed for the duration of the transit, but the alcohol stayed on board . </P> <P> A 2004 survey by the National Alcohol Beverage Control Association found that more than 500 municipalities in the United States are dry, including 83 in Alaska . Thirty - six of the 82 counties in Mississippi are dry or partially dry . In Florida, three of its 67 counties are dry, all of which are located in the northern part of the state, an area that has cultural ties to the Deep South . </P> <P> Moore County, Tennessee, the home county of Jack Daniel's, a major American producer of whiskey, is a dry county, so the product is not available at stores or restaurants within the county; however, the distillery does sell commemorative bottles of whiskey on site . </P> <P> A study in Kentucky suggested that residents of dry counties have to drive farther from their homes to consume alcohol, thus increasing impaired driving exposure, although it found that a similar proportion of crashes in wet and dry counties are alcohol - related . A study of Arkansas noted that wet and dry counties are often adjacent and that alcohol beverage sales outlets are often located immediately across county or even on state lines . Other researchers have pointed to the same phenomenon . Winn and Giacopassi observed that residents of wet counties most likely have "shorter distances (to travel) between home and drinking establishments ." From their study, Schulte and colleagues postulate that "it may be counter productive in that individuals are driving farther under the influence of alcohol, thus, increasing their exposure to crashes in dry counties ." Data collected by the National Center for Statistics and Analysis (NCSA) also support the claim of higher rates of DUI accidents in dry counties, "dry counties had a fatality rate in drunk driving accidents of 6.8 per 10,000 people . Conversely, wet counties had 1.9 per 10,000 people ." </P>
