Good question, really. See the 'About Us' link here or to the right here for the 'bare bones' company history wise.
For 50 weeks in a row each and every year for literally decades now, we show up, period.
Ok, hurricanes and/or bad tropical storms are 'bears' but the individual store employees tell us which roads aren't flooded and we drive accordingly.
Usually in the worse flooding conditions, one week's delay is 'normal' in the lower lying locations.
Put it this way, we've never been 2 weeks delayed due to flooding concerns EVER to undamaged locations.
