Our High School (East Valley in Spokane Valley) does have released time seminary. The other high school in our ward boundaries (West Valley) has early morning seminary. I grew up in an all-Mormon town (Laie, Hawaii) and have spent some time in Utah. I think you'd enjoy Spokane. There is a pretty decent-sized LDS population here, and the youth program is jam packed with stake dances and all of the normal things like youth conferences (this summer they're going on a pioneer trek_. Missionary work here is strong as well, our ward sees lots of baptisms and another one ward in our stake just split last week. The general population of Spokane is quite religious, which is a better atmosphere than some cities I've been in where people don't make God part tof their lives. On my street there are three LDS families, and the recently-released bishop lives two streets down from us. Of the neighbors I know (I don't know all the people on my street!), all do attend a Christian church on Sundays. Our next-door neighbors invited the missionaries to their home for a first discussion. Hope that helps!
