That's so sweet of you,
Mithalwen, to find that link, and thank you
Mr. Hicklin for the advice.
This is what makes the Downs such an exceptional community, from one side of the pond to the other.
Perhaps I can reciprocate and offer suggestions on how to handle your 30 cm of snow, seeing as we regularly have three to four feet and I live in a mild winter area. Makeshift toboggans for use at Hampstead Heath can be made from laundry hampers (plastic ones of course) and even garbage bins, although rubber tire tubing (inflated) is a scream. A snowball fight in Trafalgar Square would be a blast, too, with Nelson looking on.
Tolkien however seemed to think snow a malevolent thing, given Caradhras and Helcaraxë, much like Tuvo the wizard king. Pity.
