 With "Bug" being so unpopular, Cook derived a town name from Spanish; knowing was the word for cedar, he replaced one letter to make the name unique, settling on "Sedro".Sedro, on the northern banks of the Skagit River, proved susceptible to floods.In 1889, Northern Pacific Railway developer Nelson Bennett began laying track from the town of Fairhaven, northwest on Bellingham Bay, and real estate developer Norman R. Kelley platted a new town of Sedro on high ground a mile northwest of Cook's site.
