Dude, try Ann Arbor. We'd go down to Yost once a year for whatever game my dad got free tickets from a friend, and before weed was legal you could certainly smell it near frat row or a house party. Now that it's legal, go down on a Friday night and you can smell it every other block along State St. and the surrounding neighborhoods. Heck, sometimes even right outside the arena. I will say, some strains do have a stronger smell than others.
When I'm going out to some obligatory soiree where I know there's going to be a big crowd of strangers, so I need to assuage my anxiety and temporarily boost my charisma score, I just take edibles. Far more discreet, better for the lungs, longer lasting, and less annoying to non-users.
