Religiosity in the U.S.

Interestingly enough, throughout the U.S. there are varying amounts of religiosity.  For instance, the South as a whole claims higher rates of adherence than say, the West or the New England area.  In the west, and in Colorado in particular, there is a growing group of people unaffiliated with any religion (so-called "nones").  Actually, a correlation can kind of be seen between these religious differences and political divides found throughout the country.  But I digress.  Anyway, what I'm really getting at here is that a new Gallup poll came out recently that found the most, and least religious cities in the country.  Not surprisingly, the most religious places were in Utah, which has a large population of LDS affiliates, and the South.  And guess what city came in a close second for least religious city in the U.S.?????? I'll give you a hint...We live there. 
Yes, Boulder, CO came in pretty much tied with Burlington, VT for the least religious city, with only 17.3% of the population classified as "very religious."  This is opposed to the 77% found in the top city of Provo, UT.  I can't say this really came as a shock, but I still found it interesting!
Here's the link to a Denver Post article talking about it as well as a link to another Gallup poll measuring overall country wide religiosity:
