Rugby in Argentina

ok, so a little strange question. I am traveling for an undetermined amount of time. i would like to spend some time in argentina. I would love to be able to get in with some rugby while i am there. just watching would be great but i would love to find a small club where i could play a little. Does anyone know of anywhere i could find info on doing this? i am not sure when i will get to argentina, so it will depend on the sport's season. any advice is very appreciated. thanks, colin
