Well, there are a couple of guys in Spokane. One is teaching a Modern Arnis blend at Family Karate Center in north Spokane and another is teaching a Modern Arnis blend under Bram Frank at the Sharp Shooting Indoor Range complex in the Spokane Valley near the Community College. AFAIK neither were training in FMA exclusively but as a component of their overall curriculum. As far as Idaho, there is a JKD/Kali club affiliated with Hock Hochheim in Post Falls, ID. There was also a group a few years back in Moscow, ID teaching a blend of Kenpo, Thai Boxing, and Kali called Moscow Thai but I dont know if they are still around. If you spend some time looking around you will probably find a fellow student who has some training that might want to teach. There are students from all over the country who come to WSU along with a large international student population too so finding someone to train with might be easier than you think. Try contacting the TKD club and see if they know somebody training/teaching FMA. Other than the above, the only actual FMA only commercial school in eastern WA and north Idaho is the Academy of Manaois Eskrima in Moses Lake, WA which is about 100 miles west of Spokane on I-90. I train at this club and would say the FMA training is some of the best I have seen on the west coast.
