This is my experience and my understanding. You can get a TN at any Class A POE, BUT you must be entering the country. So you can get them at Class A Airport POEs if you are flying into the US, but you can't just drive over there while you're still in the US. If you find out anything different, please post because I'd love to be wrong. When we went to Mexico the first time, we went straight to the booth, but we were sent out to take the walk across the bridge into Mexico and back into the US to apply. We were in Mexico for 20 seconds, but that all it took.
