Speaking of that big Mexico-to-Canada highway through the US

There was a horrendous accident in northern Mexico earlier today - at least 37 people are dead, and scores more injured.

Now, there are accidents frequently in the US, but they're not trucks full of dynamite.

And as of Labor Day weekend, we're letting Mexican trucks drive through the US unchecked?!?!?!

UPDATE: In continuing tracking of this article, I've found that apparently hazardous load trucks aren't included in the "free flow of traffic" (yet). GOOD.
