Ask if we speak English.
True, geographically, Alaska is right up there next to Canada, and no, Alaska does not come into contact with any of the other 49 US states. But we gained our statehood in 1959 and are well aware of our status as Americans (and lest we forget, the IRS is always eager to give a reminder).
Therefore, yes, we do speak English (as do most of the Canadians between Alaska and the rest of the states) and yes, we even use US currency. Brush up on your third-grade history and geography before someone dumps you in a snowbank.
