Canada Customs Department

There is almost always a small lineup to get through the border. It's efficient and well run. However, unlike most border crossings, there is no sign on the road leading into the border to say "turn around here" if you don't want to actually go through the border. By the time you realize you have gone too far, there is a double line and then road spikes behind you. Our guests have accidentally ended up going through the border - it's a hassle, because of course they don't have passports and have to tell the staff they had no intention of going through. I did it myself and the border patrol ended up writing that I was denied access to the USA... although I had never wanted to go to the USA in the first place. I was just going to show a young person that the border existed because he had never seen it and lived in the area his whole life. Our guests said that there were others in the same situation sitting in the border patrol office. Could I suggest a sign be placed where people could be informed they needed to turn or they would be going through the border by accident?
