July Days

I can foresee an age, after the horrific end days of climate change and the advent of time-travel, when sunny days will become a form of temporal currency. "I'll swap you my portal to the last white Christmas for my portal to the last sunny week in July." "Not sure about that, mate. At least we'll see another white Christmas when the next ice age rolls round. Sunny weeks in July, though; they ain't never coming back."
