There is a rare but deadly amoeba that has caused the death of 3 boys this summer in FL that lives in warm water lakes. You would never think something like this could exist - it enters the brain through the nasal passage and if not caught right away causes death. I just thought everyone should read up on this and be aware. I would think this could occur in any part of the US where summer temperatures have heated the water and drought conditions have lowered lake levels.
