Almost exactly two years ago, Ithaca had record heat, and we posted here on IBlog an entry about hot beverages as a palliative for over-heatedness: method, or madness? It's too hot to retype or recap it here, so we simply refer you back to the posting, from 7/11/11. There's a search field on the blog pages that will find it for you if you enter "hot beverages."
Meanwhile, we got the idea of sticking our shirt into the freezer for a while before donning. We haven't done it, and are sure it is stupid enough not to mention again, but if we do it and it's cool, so to speak, we will, don't worry.
We will also report what we find when we log onto Amazon and Etsy and look up "ice-pack hats."
