Being from Vancouver BC, I know some people in White Rock. Probably more cameras there than a TMZ stakeout in Hollywood.
Even back in the late 90’s before 9/11, we accidentally crossed in to the US and the border guys just gave us a LONG sermon not to do it again. And this was before 9/11..
Even in the 50s and 60s it was not a good idea to fool around with the Canadian-US border nor border agents. Especially if you were not a citizen of either country.
