There is a chappy in HK who has dedicated himself to educating people about dolphins, who I am pleased to call a friend, and I recently went out on another tour/trip with him.
His name and facebook contacts are Thomas Tue(海豚哥哥) . Eco Association 環保生態協會
He has a great success rate, and the snaps I took that day are below.
Yes, that is me at the back and Thomas at the front...in, er, pink.
