Where I live in Kentucky, a dry county doesn't have an exception -- 0 sale of alcohol in that county, period. I grew up in a dry county and I went to the city as a kid and was shocked to see cases of beer in Walmart or the gas station. Today, my town has went from "dry" to "moist" (restaurant only sale of alcohol), to wet -- but it definitely is a culture shock to enter that scenario from any angle.
