Solar panels glimmer in the afternoon sun in Boquillas del Carmen, Mexico, Wednesday, July 21, 2004. Access across the Rio Grande from Big Bend National Park was cut off by the federal government in May 2002 in response to the Sept. 11 attacks. The crossing brought a steady stream of tourists to the town and residents were allowed to cross the border for their groceries. Photo: JERRY LARA, San Antonio Express-News / SAN ANTONIO EXPRESS-NEWS
