If they put pictures of missing kids on beer instead of milk, we'd probably find them in about 20 minutes.
According to HuffPost in 2010 American consumption of liquid was as follows:
Rounding out the top three is bottled water at 28.3 gallons and beer at 20.8 gallons.
Also making the cut:
Milk, 20.4 gallons
Coffee, 18.5 gallons
Fruit beverages, 11.5 gallons
Tea, 10.3 gallons
Sports beverages, 4 gallons
Though I'm curious about their command of mathematics or english! So it looks as if the notice should firstly be on bottled water.
