...it refers to the "subdivision invasion" proceeding at a varied pace in what's commonly referred to as the "second ring suburbs".
As more & more bourgeois pigs move out beyond the "first ring suburbs" - the towns which border directly on the city of Buffalo - they have begun spilling out into towns in the "second ring", whose "inner" borders are the "outer limits" of the towns directly adjacent to the city. Presumably this is to escape the congestion & development of the suburbs right around the city. The concentration of people drops off pretty sharply just 15-20 minutes outside the city, and a lot more of the land is still utilized for small-scale farms - though it's pretty much exclusively cows rather than pigs where there are animal herds.
There's a dairy farm about 5 miles away where they grow their own fodder as well which is the source of a decidedly "aromatic" air when the proprietors utilize the fertilizer supplied by their bovine charges to nourish the fields where they grow corn & some grassy plant to serve as cattle feed.
The signs seem to be a facet of the response of the town gov't. to its new inhabitants' desparaging of such fine old traditional practices. I actually had a brief conversation with a worker at the "pygmy Post Office" in Marilla prompted by her complaints that "all these yuppies moving out here" were pissing & moaning that the farms... ...well, smelled like farms !
I know that there has been a bit of a turnabout of the attitude toward development of the towns around here. Initially, the influx was welcomed as a means to increase their tax bases, but all of a sudden the realization that the people moving in in droves in recent times wanted crapola like the "mini-marts" on every other street corner & other such commercial development they'd left behind wherever they'd come from - which, keep in mind, ain't exactly all that far away... ...I mean - I'm about 18 minutes from the Southeast edge of Buffalo, and even less from the "inner" suburbs. Now there is a more scrutiny of development projects, though I still find every now and then while driving along a road I haven't travelled in a while that a cul-de-sac which looks nauseatingly like something out of a cliche image of a suburb has sprung up.
Mostly this just makes me wonder where the fuck the people living in the thing are doing for a living to make the money to buy their nauseatingly ugly "McMansions", and where the fuck did I go wrong career-wise ?
