What a wonderful journey, my friend! And for you is no other better way of ending those day with some fun dive activity. Impressive how can be possible to spot sting rays a few meters away from the shore, and only with the snorkeling equipment. Can't wait to see the selection of the underwater fotos that you taken. Pretty sure that some of them would be very decent and very interesting. I've placed my bet :)
Have a great weekend, and enjoy it to the fullest!
