Worst US/Canadian border crossing

Our "worst" crossing out of over a hundred was a 20 minute delay for a secondary inspection going into Canada via the Lewiston-Queenston bridge. The officers were very polite while checking our coach, and even directed my wife to a spot where she could walk our dog. As said, they never looked in the storage bins, and even though they asked me to unlock it, never looked in the toad. When the officer was done inspecting inside the coach, I asked him why we were selected for the secondary, and he said it was just a routine random selection. He told me if any adverse information had popped up on the computer, it would have been a much more thorough process. We've had longer delays in traffic waiting to cross than the inspection took.
