FSX. Orbx shows off two screenshots of Skagit KBVS, another addition to NA BLUE Pacific Northwest. A general aviation airfield with a long runway (5300 feets), located between Orcas, Diamond Point and Concrete.
Hugh Johnston is designing Skagit. He also made Cessnock and worked on Canberra.
No indication from Orbx but KBVS might be released right after Bowerman and Fall City.
