That’s quite appropriate. Alberta is a sort of honorary US southern state, just colder, but with the same brain-addling properties as Texas, arising presumably out of either oil fumes in the air or the mandatory wearing of cowboy hats that are much too tight and impede the circulation to the brain. This causes the afflicted patient to develop a hatred for liberals and all forms of government, and to employ expressions such as “Yeee-haw!”. Eventually, the patient is motivated to install the horns of a deceased bull on the hood of his pickup as a sign that the insanity has now fully set in.
Still, the cold appears to have a mitigating effect on the brain damage. Sam is at least more literate than most wingnuts – his lunatic RW ravings are at least grammatical. When Sam wishes to reference, say, the perils of evil anti-business climate-change-believing socialist government, his grammar and orthography are impeccable. In this way he can be distinguished from Texans and other American RW lunatics.
