An experience like no other! Nothing prepares you for the first time your holding on to that bar looking down at the lit up water below and you see these huge animals gracefully sweeping underneath until they turn upwards, mouth and gills wide open on a directory straight for you, only to flip inches from your face, so close that you look each other in the eye, see the white of its belly, count their spots and be impressed by there long tails and overall sheer size and grace.
