Word of the day: rifty

A strange word of the day today, in that I'm not sure who uses it, what it means or where it comes from. This copy was submitted to the subs' desk earlier this year by an English journalist based in the States:

It’s mid-morning on a bleak January Sunday in Detroit, Michigan, a city much favoured by producers of disaster films because they don’t need to spend much on dressing the set. It’s a rifty old place, boasting an ambient temperature somewhere south of very freezing

The context seems to suggest that rifty means 'cold', but I haven't come across it elsewhere before or since. My Concise OED and Google aren't much help either. Anyone out there use 'rifty' at all? Or did our writer just make a typo?


Detroit in winter is, apparently, rifty
