The numbers are that high?
Then again I live in the bluest region of the state. It's a real struggle for our church when so many other organizations (soccer, baseball, youth orchestra, etc) treat Sunday as just another day in which they can schedule attend-it-or-forget-it morning events for the kids. At least we get to see the parents' commitment.
After spending two years in Seattle, and visiting my sister several times in South Carolina and now Tennessee, I can honestly say that my homestate of New York and my current state of residence, New Jersey, are somewhere in between, although aggressive proselytization has always been “frowned” on, with religion considered a private matter outside of Christmas displays. Nevertheless, the secularization trend is evident by several indicators.
I live in the heart of Paganville (the Seattle area ) where, judging by church attendance, most people avoid church all to gether.
