I was in that area early April. N1gdo sent me a ton of info on the south coast. I did get a chance to check out Punta Solimon. Very fishy. No guides. no licence, no worries.
Except for one tour guide that gave me a hard time as I waded out, everything was good. He was easily dispatched once he was made aware of the facts. There's alway one in every crowd.
Thanks to Frank I caught some fish on my trip.
