Yes, Surrey is right next door. That's why I said you were partially correct. (Half the picture is in the US, however.) If you've ever been to the Peace Arch park, the Arch was right behind me just down a little hill. And, yes, palm trees can grow in this area. I live in Oregon and have one too. That would be the Windmill palm which originally comes from Switzerland. There actually was one just a few houses up from "0" (Zero) road that you can see in the first picture.
Here's one more picture. It's about 15 miles E of the Blaine/White Rock area. It's on the line but in a more rural setting. The nearest towns are Lynden, Washington and Aldergrove, British Columbia. You can see two parallel roads. The one in the foreground is in the US. The one across a small ditch is in Canada. That's all that separates the two countries here. As I was taking this picture a fellow was mowing his yard on the Canadian side. He smiled and waved. (He probably sees his share of border tourists!) The ever present border patrol passed by as I took my picture. If you look to the right you can see the tall steel tower on which is perched the heat sensing cameras.
