I could not get my truck into Mexico, so I have turned back. I'm currently sitting in Ponca City, Oklahoma, on my way back to the Great White North. I will then book a flight to Mexico City, but that will probably be three weeks or a month from now to take advantage of lower fares. Gotta run--there's an icy storm blowing in--but I'll be back tomorrow, and I'll have a few things to say about bureaucracy and corruption on the border, "Fourth Amendment-free zones" along the border, and all those Texas highway patrol cars lurking on US 281 coming out of the Rio Grande Valley.
