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?
