When a familiar looking man got out of his car and walked up to Joe Linder's hot dog stand at the corner of Fifth and Lookout streets on Friday, the Chattanooga entrepreneur had to do a double take. It was former UT Football Coach Phil Fulmer. He was in the Scenic City to pick up his grandchildren, according to Mr. Linder, who was wearing a Big Orange jacket and refused payment from the coach for one of his specialty Pops Dogs. Mr. Linder said he asked the coach when he was going to become the athletic director at UT. “I can't accept the position until they ask me,” he told Mr. Linder, who has a Facebook website (Pops Dogs) to inform readers where and when he will be selling hot dogs on certain days.
