The effectiveness of concrete vehicle barriers....Biglorryblog offers a 'pause' for thought!

Last one for tonight and it's a real doozie. Gary Richards sent me this (I'm assuming it was sent on to him by a colleague)...Anyroadup he says: "Guess you might have seen this destructive testing....the barrier maker would be happy with that outcome!" Naturally he then suggests that the outcome might have been different with a Mack truck but it's probably wishful thinking on his part...Meanwhile, I don't know who to credit for the video clip although I trust they won't mind me sharing it. It appears quite a few times on YouTube. If you know who did take it I'll happily credit them...or remove it if it causes a problem. According to Gary's e-mail it was sent by someone who works for the Army Corp of Engineers and shows the effectiveness (and how) of a concrete barrier in stopping a truck.
