Hey, I will be in Sao Miguel Island (Ponta Delgada) from August 1 to 6th and plan to do as much diving as I can while I am there. I spoke to a few dive shops that said if I can organize a group of 6-8 advanced level divers - they'd consider a trip to Ambrosio to see the mobulas (manta rays) and whale sharks. Please let me know if you're interested in this! Would love to see if I can get a good fun group together.
