Hehe... so I found Prowl or Barricade one posing as a police cruiser on a recent trip to Costco...
After I took these shots, the officer driving the car came out and asked what I was doing. When I told him about the whole Prowl/Barricade thing he laughed and said he was pretty sure it wasn't Cade for the simple fact that he hadn't noticed any caffeine addicted hackers tagging alone. I laughed... least he was a TF fan....
Edit: Btw, I'm aware it's not the "real" Barricade, but some fanfic stories will show Cade as having changed designs to a Charger and some show Prowl as one. So... just wanna make it clear. I'm not stupid. I know what Barricade was in the first movie.
