I'm an urban / suburban guy now but I grew up either living on a farm, or working on one, until I was 17. My dads only job his entire working life was as a hired hand on the family farm and allowed me to have a bit of connection to that life even after I became urban. You know how people say have what they refer to as comfort foods?..... Well I have what I call comfort odors, one of which is 'barn smell'. That feed-room + hay-loft + farm-animal-shit combo than can exist when the shit is reasonablely managed and not overwhelming. Like the one that exists in the livestock barns at a state fair. The primary reason I attend the state fair here in AZ is to stroll thru them, take in the aroma, and enjoy that 'comfort' feel it induces while I look at all the animals and let fond memories flow thru my head for a few hours. Then I switch to eating all the bad food the fair has to offer.
