Imaworkinonit, Yes they do have churches there ;-) I've been to two in Longmont, two in Boulder, and several in the Denver area. Even one in Ft Collins IIRC.
There is just one church in Boulder, and one in nearby Louisville. Not sure if either had flood damage. The one in Boulder seems to sit low, where water would run into it rather than away from it. Haven't driven by there since last Wednesday, so am not sure.
