I just passed customs and checked in my backpack. I'm on my way to Houston where I'll transfer flights for Cancun. It would seem this is not the best time to go to Mexico, with outbreaks of the swine flu and an earthquake in Mexico City. Hopefully the Yucatan Peninsula (where I'll be spending all of my seven days) is not experiencing the same conditions.
I'm feeling a bit anxious, as this was very much a last minute trip and I've never done a trip where I've rented a vehicle for the entire time. It will be interesting.
