The Colorado River is located in the southwest of the United States and northwest of Mexico, with a total length of 2333 kilometers. The Colorado River is only part of it near Las Vegas, but it's all in the Grand Canyon, not deep enough to see the Colorado River. I participated in the helicopter + cruise ship project, totaling $100. To take a helicopter, you need to measure the passenger's weight and take a seat in the designated seat after weighting. I'm honored to be seated in the co-driver's seat. Helicopters hovered in the air and watched as they landed in the canyon before cruising the Colorado River in cruise ships. Then he returned by helicopter.
