Can You Smell That Smell

[Betty]

Every day on my way home I drive through the 15 / 91 overpass (going south on the 15 to the west 91 - or I think it's south and west anyway.)

About 1/3 of the time there is a smell as I drive on the overpass. A bad smell you're thinking? No! That's what makes it odd actually.

Some days it smells like cookies. Other days it's bubblegum. There was a grape smell one day. There have been other pleasant smells as well but I'm not recalling them at the moment.

I refer to it as the scent factory. But I wonder - what in the heck is making those smells? Is there a cookie factory over there? That would explain the cookies but not the other smells so that can't be it. Besides, it would smell like cookies every day then, wouldn't it?

So - can anyone tell me - what in the heck makes it smell like that?
