4 inches of snow and the world stops

so apparently all it takes for my area to shut everything down even Walmart, Walgreens adn the post office is 4 inches of snow. well we are expecting more tonight. 3 of my husbands coworkers from the saw mill he works at are sleeping in our kids playroom downstairs, because they didnt cancel 3rd shift last night and by the time they got off this morning it was 2 late for them to make it home.
