I finally did it! I finally crossed the first border. There were no complications at all and I safely arrived in Monterrey, MEX. I am glad that I didn’t do this trip yesterday anymore because it did take a little longer than the expected 7h of driving. But having left this morning at 6am, I arrived comfortably at 5pm. For the first time I had some time for doing some sightseeing in the city I arrived at. It was an interesting experience until the point when it suddenly started raining cats and dogs. And by suddenly I mean within 5 min after a clear sky.
Tomorrow I plan to get up as early as today to make it all the way to Mexico City.
