Do any of you camp/RV down in the Brownsville, Texas area, or along that "Camper Alley"? A friend and her hubby go down there for 3-4 months and she said "you don't want to drink the water down there". I didn't get a chance to talk to her any more about it so would like some input if any of you have been there. We have a water softener, a filter, and we also use a Britta pitcher in the RV. Would all those remove any "crud" that would be less than healthy from the water or should we use bottled water if we go there?
