The May 1, 1909 NYT reports:

DETROIT - At midnight tonight 585 saloons and ten breweries in nineteen counties of Michigan which voted "dry" at the last election closed their doors. Thirty of the eighty-three counties in the State are now "dry." Stocks have been closed out at reduced rates in many instances.

I wonder why the "stocks" had to be closed out if there are counties that are not "dry"? Perhaps there were limits (like today) on bars selling to other bars. If you were a bar owner in County A which was going dry, why not purchase a liquor license in County B and open a bar there? Perhaps there were limits on the number of bars that could be opened in non-dry counties?
