We sped downhill on smooth blacktop towards San Pedro. Within 45 minutes of leaving Bolivia, we'd descended 5,000 feet and gone from 30 degrees to 75. It's so much warmer here that even immigration won't set up at the border - our minivan drove us directly to the inspection point at the edge of town. We got off, filled in some forms, got our luggage x-rayed, passports stamped and got back in the minivan for a five minute drive into the center of town.
