We were traveling from Larado going up 59 through freer . Strange question got asked at the Freer checkpoint, That's never been asked as many times as I've gone through a checkpoint. They asked if we were carrying anything radioactive . I'm just wondering, I haven't heard anything about worries for illegal radioactive materials coming over the border but it just seems odd that this question would have been asked for the first time in 6 years. Has anybody heard anything?
