It's called a city, captain obvious. Try walking in the woods if you don't want to smell civilization. Pizza Luce smells like cig butts because people have to go outside to smoke. If you want to smell their delicious pizza, walk past when they're actually open for business, or better yet, go in and buy one. What's next, some heavy hearted disappointment over the aroma eminating from WLSSD? Come on. I'm as liberal as the next guy, but jeez...

We can smell alakaf roasters at Enger if the winds are right - sometimes mixes the sweet smell from superwood. Woody Java, mon. Aaah.

Angela's smells better than Peterson's? I can't smell Angela's from the street, but walking past Peterson's in the skywalk is rather nice.

Weird smell: the steam vents. Why does it smell like that? I always hold my breath, assuming it's the scent of some poison added to the steam to kill mold that might grow in the humidity...which is probably completely paranoid, but what do I care?

I'm pretty basic, so Famous Dave's does it for me.  If the timing is right, I'll get a nice aroma off of the thai place nearby.  Those are not subtle nasal flavors, I admit.  The steam tunnel comment is funny, because I always felt the same way.  I never noticed Luce smelling like burnt nicotine, but I haven't been by there recently.

The west duluth McD's and Kentucky Fried -- in combination -- you can smell all the way from near the highland cemetery if the wind is right.  Kind of a mealy/greasy french fry smell that for some strange reason actually makes you salivate even though you're disinclined to frequent fast food spots and salivating near a cemetery makes you question your sanity.  

No I'm just kidding (about food choice, not the smell); I do love my fried potato thingies and chicken nuggets with mysterious sauce.
