It doesn't take insanity for drowning in the American or Sac Rivers. If it isn't windy, the river looks very calm and serene with many sandy beaches. But this time of year the water is mostly snow melt and very very cold. It is also full of undertows. And the sand suddenly drops off! So a person walks out into the river in the soft sand and in one step is in very deep, cold water with strong currents and undertows. Even if you are a good swimmer, you will have trouble---especially if you panic! A PFD will help you survive, but often even young children do not wear them. They are available for free along the river and from nearby fire stations. Conditions do improve later into the season, but the rivers are always something to be respected.
