Roads that smell like food

[vtk]

I-670 near Cleveland Ave smells like bread (or cinnamon rolls on a good day) from the Kroger bakery.

Eastbound only, usually.  Pretty much the whole Columbus State Comm Coll campus gets it too.  To me it smells like doughnuts.  I and other people thought it was Wonder Bread (which had a more prominent sign) until that facility closed and the aroma remained. 

As for bad smells, there's the poo bioreactor down I-71 at the Frank Rd exit, a.k.a. Rank Rd...

Strong odor of onions on I -80  while driving thru Vacaville, CA.  Maybe this has changed now, but it used to be a predominate smell.

On one of my first roadtrips as a child to Northern California, we approached Gilroy along US 101.  It was during Gilroy's garlic festival.  We continue to associate Gilroy and the stretch of 101 through town as being the garlic city.
