AUSTIN, Tex. — In April, as Texas reeled from wildfires and a drought, Gov. Rick Perry sought assistance from the federal government, but also from a higher power. He asked the state to pray for rain, issuing an official proclamation that “I, Rick Perry, Governor of Texas, under the authority vested in me by the Constitution and Statutes of the State of Texas, do hereby proclaim the three-day period from Friday, April 22, 2011, to Sunday, April 24, 2011, as Days of Prayer for Rain in the State of Texas.”
