Hi there!
To us Canadians (and we *do* get many American tourists), people often think of the "American" accent being an exagerated Texan accent...
We often associate that accent with arrogant, stupid, redneck cowboys (Athough I known several Americans, and they are none of the above!
Please don't flame me... I'm just saying what some people think!)
