Oh yes, there are worse things: chicken farms. Hog farms are certainly smelly but chicken farms are... disgusting in a way all of their own, a nauseating smell which makes you glad you did not eat a big lunch. I've lived on a (small scale) hog farm - studying at an agricultural university, being in need of a place to live and finding a farmer who had a cabin on his farm ready for rent leads to such - and have cycled through areas with chicken farms.

I studied forestry and know what I prefer on a hot summer's day, the orangey tang of a Douglas fir stand or the resinous smell in a pine forest on sandy soil are infinitely preferable over both hogs and chickens. Or weed, for that matter.
