United States Postal Service mail carrier Sue Mulkern takes a break along her mail route to cool off in four-year-old Destiney Dixon's pool in front of her home along Boyle Street on the North Side of Pittsburgh. "Everyday she waits for me," said Mulkern, "and today she asked me to take off my shoes and socks and get in and I said I think I will." Temperatures reached 90 degrees across the region and left many people to find some means of staying cool.
