On the Qiandao Lake, an international bridge connecting the United States and Canada crosses the border between the United States and Canada. The bridge is like a natural rainbow, which adds a little charm to the Qiandao Lake. In the middle of the bridge is the boundary between the two countries, with unmanned Customs on it. Qiandao Lake is a famous summer resort with beautiful scenery all year round. Thousand Island Lake is not actually a lake. It is a section of the St. Lawrence River that connects Lake Ontario and lies on the border between the United States and Canada. Over a river 50 miles long and 5 miles wide, there are more than a thousand islands of different sizes. It is a world famous tourist attraction. The scenery is picturesque. On the return trip, there were many gulls on both sides of the boat. The guide reminded everyone not to feed them.
