I visited NYC for less than a week.
Des Moines , Iowa.
For Canada it's probably Sherbrooke or ~~jonvive~~ Jonquière.
Bonus game: name the linking theme and specific things that link those places. Hint: it's not french things.
EDIT: Famous metal bands come from there. Slipknot from Des Moines, Gorguts from Sherbrooke, Voivod from Jonquiere
