I  live in N y  and like to lay on the ground outside and watch the  birds.     The only thing is my head over concerning itself about bird flu.    We here have had sunny  days that evaporate  the water out of it in the same day.  It is 2 ft  across and 3 inches deep.  So if the cycle is rapid I would guess and it is only a guess that problems from being by it are not very much at all.    What do you think ?
