I live in north-central Broward county. My sister-in-law lives in western Miami. Yesterday my wife told me that her sister needed for me to pick up a few gallons of water at the store and bring it down to her in Miami. Yeah...riiiight.
At that point I told my wife it would be just a wee bit easier if her sister filled up bottles from the same source as most bottled water...namely the tap.
This buying water insanity has always amazed me. There are places where the tap water tastes bad, but not in most areas. I keep about 5 milk gallons full of water at home at all times. Refresh every 6 months. I have taken a shower using one gallon of water. Pour a little to wet your body. Rub down with wet soapy cloth. Use the rest to rinse clean. Easy.
On a separate note, here is a good site to see visuals on storm tracks at Puerto Rico and nearby islands.
