I am sorry for your stress and worry. I would be glad to check for him when I arrive in 10 days. I don't know the beach but I can ask around Jah Bs and for the sea man you mentioned Birdman? Not sure when kim&betty are going to arrive.
Hold good thoughts - positive energy will bring good results. Although odd, I am sure there is a good reason he cannot reach you.
Also, maybe you want to post on the South Coast Message Board - there may be more people from that area.
Please let me know if you want me to check in Negril for information.
