As most of us know, seasonality appears to play a large role in the on-set of CH. It gets fuzzy in the correlation, but I find it interesting that such a small amount of people are listed on the "where we live" tab of this site that reside in Alaska. I realize that this site may not be indicative of a formal survey for that purpose, merely find it interesting that there are only 11 (I think) nearly half as many as the small state of Rhode Island.
