We have no idea what's going on here, but, apparently, he does it all the time.... (language!) According to the original post:
I was visiting my sister-in-law in Wimberley, Texas when we went to cross over this little bridge and over to the neighborhood across the way. She had just started to tell us the history of truckers being poorly directed by GPS, and getting stuck in the river, when we ran into this guy. We had to back up from making our own crossing, and got to witness firsthand exactly the scenario she had just moments ago been describing. Somehow this particular trucker made it!
