Natchez is certainly not dry.
Mississippi went wet statewide in 1968. Not aware of any dry counties.
Booneville may or may not offer drinks, but 25 miles south is Tupelo it is also not dry.
Actually Mississippi didn't go wet but allow the counties and municipalities to vote on whether they wanted to go wet. For example, I live in George County. It and the county seat, Lucedale are dry. Immediately to the west is Stone County. It is dry yet the county seat, Wiggins, allows beer sales only except on Sundays, Blue Laws.
