I work for the Oklahoma City Zoo and ran across your photograph of the Tallgrass Prairie. I am writing to ask you if it would be okay to use this photograph for a sign here at the zoo. You will be given photo credit. This will be used for a "Non-profit" sign on zoo grounds. Beginning on Nov. 1, 2007 all state zoological parks will be "Smoke Free" and the sign title is.... 'A Breath of Fresh Air.." explaining the new state law. I thought that your photograph really portrays the above quote. If you have any questions, please contact me through my email. Please put a subject for the email so it will for sure get to me. Thanks, and great work!
