I'm in New England for the winter solstice holidays. Generally I arrive hoping for snow and getting a light dusting that blows away after a day, if that... some years it's in the 60's and I walk around warm without a jacket.
This year, blam, a foot or so of powder.
I hadn't packed proper footwear, just a pair of sneakers, knowing that I'd be walking around NYC a bit and thinking there would be little snow. Ended up buying a new pair of boots just for this week!
