Finally made it to the checkpoint. It was somewhat disappointing. The CBP officer who checked our car was...in my opinion...not motivated or professional. We could have had a carload of drugs, illegal aliens or terrorists...and he just waived us through. Though my friend Larry and I are gringos...we had Carlos and his friend in the back seat. They never even asked them any questions, let alone check their residency documents. All the women rode in a separate car. They were just waived in too...and they were all Latinas.
