Just received our "he's here!" email from the Washington Kennewick mission office! I finally know where Elder Sedlacek is--besides knowing he was in WA or OR.
Dun dun dun dun.......he is in Ellensburg, Washington, about 2 hours NW from Kennewick.
This is what is being referred to as "the Sacred 37" with President and Sister Ware in the middle. Elder Sedlacek is up on the back row, 6th from the left. What an amazing thing to be part of--the first huge influx of missionaries since the October 2012 announcement from President Monson about missionary age changes. Thus the name, "Sacred 37."
