Raining

It has been raining all day yesterday, but luckily today the sun has come out again.
Anybody can help me? Am I allowed to stay 3 months in Argentina with my tourist visa, or only 90 days, as I have July and August in my current 3 months that makes a difference of 2 days.
Anyway, I have made up the plan to go to Assunción, Paraguay and from there go either way to Ciudad del Este and Iguazú or to Encarnación and Posadas to proceed further to ba, run the marathon and return to Salta.
The job in the busterminal is horrible at times, you spend hours ans hours in the terminal, by now I know most of the people who work there, just from the people that work for the buscompanies selling tickets I still don't know all the names.
At the moment half the city here is barricaded as the 2 biggest football clubs play at home. Not the the club with the fiercest hooligans though.
