What an interesting name, Where did you get that from?
I have fished at Boca Paila a few times and further south at Casa Blanca.
My recollection is that there are lots and lots of very small bonefish around and a lot of permit. It sounds like they have gotten very spooky.
The journey to Boca Paila is a nightmare and going further must drive you crazy. The flight to Casa Blanca from Cancun is only half an hour and they used to have daily tourist flights. That maybe usefull for future reference.
