I'm not a big fan of Anchorage, AK as a bike commuting place myself. A lot of the roads are like Northern Lights Blvd, on which I did many a commute among motorists who like to go 55mph (in a 40mph zone) and pass too closely.
regarding the "no Canadians yet?" comment... I found Montreal to be pretty good. Drivers in center city, at least, usually treat bicycles like any other traffic, to be passed with several feet of space at a minimum. Lots of roads where actual traffic speeds are 30mph or less.
Philadelphia, where I now live, is also a good bike-commuting location, with many light-traffic, low-speed streets to take you to almost any destination, plus bike lanes along some of the popular cycling routes. (the bike lanes are mostly painted dangerously close to the parked-car door zone though! big thumbs-down for that; I don't want my fellow cyclists getting doored.)
My current commute takes me through the Philly suburbs which are really not so bicycle friendly, although it could be worse.
