Hull: The central part of this city, and the most city-like by a longshot. The downtown is a few blocks of government towers (aka boring as fuck), but now and then, the clubs there get RAIDED by swarms of people from the region and 18-year old Ontarian alcoholics. Can be a pretty seedy place. Outside downtown, it is not so bad (aka boring).
Gatineau (the ACTUAL Gatineau): An overgrown hick town. The best way to aspire for more is to get the hell out. Lots of youths getting too into the gangsta life (despite it being a suburb). Aggressive French Quebecers who try to defend a culture they barely understand or know, while the rest of Québec laughs at them.
Aylmer: Quaint, historic, and predominantly English. Has a small-town vibe to it, and a huge proportion of teenagers. Crazy parties all the time, and tonnes of drugs. Has a beautiful marina that hosts a large St-Jean celebration.
Masson-Angers: Largely an oversight where people rarely go in and out.
Buckingham: The most hick you can get. Take Gatineau, make it even more boring, and add the fact that it's tiny and far away from anything, and you'll get something like that.
Guy 2: "Don't you mean Gatineau?"
Guy 1: "NO I MEAN HULL, YOU FUCKER."
Guy 3: "Yo guys, party at my place in Aylmer!! Let's get fucked!"
