Rochard is correct, building a wall on our southern boarder will not stop illegal aliens from getting into the USA. There are many other ways to come to America illegally. one way is crossing the Canadian/USA boarder. When i was looking for property in Maine i was taken to a restaurant by my realtor which just happened to be in Canada we crossed the boarder via Route 1 without being stopped as there was no one on duty and the barrier was raised. 2 hours later we crossed back into the USA again without being stopped as the crossing was still unmanned. Since then i have been back to Canada 12 times and every time no-one on duty. ( after 6pm )
So is Chump going to build a wall on our northern boarders and get Canada to pay for it ?
Hiking the appalachian trails will also get you into Canada or vice versa as long as you like black bear
