One in 5,000 people have Hereditary Hemmoraghic Telangiectasia, but fewer than 10 percent have been diagnosed.Local resident Celeste Farr would like to increase awareness of the disease by holding a Walk-N-Rollathon on the walking trail at McMinnville Civic Center on April 23 from 1-2 p.m. If it rains, the walk will be moved to April 30. “My son Jason passed away last year and he was struggling with HHT. That was one of the reasons I decided to do this. I’ve been thinking about it for a couple of years, but this is the first year I’ve decided to go ahead and do it,” said Farr.Farr’s mother, Elaine Vachon, and her daughter, Elaina Farr, also have the condition.
