Leslie Kidwell Robertson of the Revitalize Port Angeles Facebook group took a red-eye from Seattle to Chattanooga, arriving on July 29 with signed sympathy banners for the people of Chattanooga.
The two cities were fierce rivals in Outside magazine's Best Town Ever contest, but buried the hatchet when a 24-year-old gunman opened fire at two Chattanooga military installations, killing five service members.
Robertson will present the messages of sympathy in a ceremony on Thursday.
"All the people I've run into have been so excited to hear where I'm going and why," Robertson told the Peninsula Daily News. "It's funny, people like to touch the package with the banners."
According to the Peninsula Daily News, there are 16 different banners, which were flown to Chattanooga thanks to frequent-flier miles gifted by an anonymous donor. One banner, which was displayed at the Port Angeles Walmart, received so much attention that it had to be switched out with another banner, the Daily News reported.
