I will arriving on on January 5th and staying until the 25th so at least some days will be open. Juan M., Thank you very much for the links to the regulations and licenses. I was wondering where to get those, I will be sure to read them thoroughly. Feperando, thank you for the offer. I would love to try my hand at kayaking the rivers there. It is such a new environment for me. Here we just have the ocean and lakes for kayaking. The rivers in California are much further north from where I live and smaller than what I have seen of the rivers north of BA from pictures. I will be in touch, Guadalupe and I must coordinate our plans. I really appreciate all of this, I know how to fish where I live very well but wouldn't know where to begin in Argentina. Thank you all for sharing your knowledge of your fishery with me.
