The Subtle Seattleite
Between their appreciation of fine ales and familiarity with enlightened drug policies, they can be difficult to distinguish from the locals at first glance. If they try (unsuccessfully) to argue the virtues of The Gorge over Red Rocks, you'll know.
The Transitioning CU Grad
After five or six (seven?) years in Boulder, he's decided it's time to try to break into the brewing industry. Note: "break into" means attending numerous happy hours for as long as he can get mom and dad to continue subsidizing the rent.
The Insufferable San Franciscan
Relocated here for important business reasons that he'll happily tell you about, but not before unfavorably comparing Denver to SF three or four times in a single sentence. Eventually, he'll realize all his former city has going for it is a crippling cost of living and rampant public defecation. Or he'll move back and no one will mind.
The Herd of Iowans
Man, people from the Midwest really crave mountain views, don't they? Iowa in particular seems to direct so many inhabitants to Denver that it's amazing there's anyone left in Iowa. Raising livestock predisposed to herd behavior must have really made an impression on their psyche back home, because they invariably seem to roll in tight-knit packs of like, 20 people. If they're decked in Hawkeyes gear and headed to a bar... avoid that bar.
