We have now been in Mexico for 6 months. We were reminded of this when our tourist visas expired and we had to go to immigrations to get them renewed. The renewal process is easy and costs just $20 each. We went to immigration office at the airport in Guaymas where there was easy parking and no waiting. The immigration officer did seem a little annoyed that we were interrupting his TV shows but he processed our new visas with no fuss. We have had a wonderful time in Mexico, the people are friendly, there is plenty of stores to get almost everything you need and the weather has been beautiful except for the last 2 months here in San Carlos where it's just down right frickin' hot. The heat index is daily 110°+ with a temp in the high 90° and humidity above 80%. It's just too hot to do anything outside. Hopefully in another month it will start to cool off.
I forgot to mention that neither of us has worn long pants for over 6 months. Short and t-shirts everyday!
