The Somerset County native had no way of anticipating that two years later he would drive for the last time. It was a chance meeting with an old friend that began his journey to legal blindness in 2007.
"We got together and shook hands," he said of that fateful meeting at a local pub near his Klondike home on St. Patrick's Day. Klondike is near the Village of Listie. His friend told Fritz that he was getting over the chicken pox, but his doctor told him he was past the contagious stage.
Unknowing, Fritz was sucking in the virus that would end up attacking his retinas. He must have rubbed his eyes at some time during the evening, he said. His vision in his right eye became a little blurry over the following weeks, but Fritz put it down to nothing more than a little irritation from possibly getting something in his eye. He had 20/20 vision at that time.
On April 30, 2007, that changed.
"I was on a delivery route in Johnstown when my right eye hurt and got all bloodshot. I couldn't touch the top of my eye," he said.
Fritz called his eye doctor and received an appointment two days later. The doctor immediately sent him to see a four-member team of specialists in Pittsburgh.
"The pain had left, but I still couldn't touch it," he said.
The team did not know what was the matter. They treated Fritz with lasers and injections and sent him home. He was scheduled for a follow up exam two weeks later.
"It didn't make it two weeks until it jumped into my other eye," he said.
He returned to Pittsburgh and the doctors told him he had Acute Retinal Necrosis Syndrome. The disease is caused by a virus that can lead to retinal detachment and blindness.
"It attacked my retina and closed in like a brush fire," he said.
"I was a scared man. I knew something was eating up my eye. I was seeing green (when the color he knew was red)," he said.
He spent eight days at UPMC Montefiore Hospital. The doctors tried to put out the fire, he said. The doctors told him that they were able to put out the fire, but what remained was like a lot of charred wood.
He could see well enough to drive, he said. He continued to visit an eye doctor every few days to check on the progress of the disease.
"It was a Saturday about noontime. I was waxing my truck, when my vision in my right eye went completely black. There was no pain. There was nothing. My retina had detached," he said.
The doctors operated. His eye was filled with synthetic oil to help with the process of trying to reattach his retina. He could see again, however, everything was cloudy because he was viewing the world through the oil in his eye. The oil would remained in his right eye for seven months. It would be removed, then eventually replaced to save his eyeball, but not his vision.
"I thought I was going to go back to work by the Fourth of July, not knowing that I would never work (drive) again," he said.
The Fourth of July came and went. By Aug. 30, the vision in his left eye had deteriorated. He voluntarily quit driving.
