Image #: 11984282    Traveling is stressful enough  but throw in nearly 98 degree temperature and it can seem most daunting. Just ask Susan Miller who waited for a bus to take her  and her luggage to the UT campus September 21, 2010 so she could catch a ride to the airport and the return home to Dublin, Ireland. Miller was one of a group of  students in the U. S. on a two week exchange program with the University of Tennessee. She wipes the sweat from her face waiting in the heat near 4th and Madison for her ride.      Commercial Appeal /Landov Michael McMullen \ FILE \ Landov
