The mission is located in the populous southern tip of Texas, 80 miles inland from the Gulf of Mexico along the Texas-Mexico border known as the Rio Grande Valley. Edinburg is located 240 miles south of San Antonio; 350 miles south of Houston; 140 miles from Monterrey, Mexico; 600 miles from Mexico City, Mexico; and only 16 miles from Reynosa, Mexico. Edinburg is part of the fast-growing international metro area of McAllen-Mission-Edinburg. It is located in the heart of the Rio Grande Valley, where more than a million people live, 87% of whom are of Hispanic origin. This enables RGBI students (in both the Bible Institute and Language School) to share in the linguistic and cultural advantages of this area. The pace of life is relaxed, and the people are friendly and helpful.
The Rio Grande River forms the boundary between Texas and Mexico. The river, which starts in Colorado, enters the western end of the valley near Roma and finishes the last 150 miles of its more than 1600-mile trek as it empties into the Gulf at Brownsville. The valley is one of the major citrus and vegetable producing areas of the United States. It has also been listed as one of the top birding areas in the world, with birders coming from around the world to see the many varieties of birds that are found here. The climate is semi-tropical with mild winters and hot summers. Approximately 200,000 tourists from all across the United States and Canada make the valley their home each winter. These tourists are known as Winter Texans. South Padre Island, a short drive away, is one of the premier beaches in the United States and receives may visitors from both Mexico and the United States.
