Couldn't get to my job today, on top of a steep hill on an ungritted back
road.

Took my granddaughter sledging instead. Amazing to see the variety of
things used as sledges; rubble sacks, estate agents signs, road signs,
small
surfboards, wheelie bin lids, trays,

Built her the sledge from some scrap timber. Runners are 6 x 1 with
aluminium strips.

I have a suspicion for some reason that aluminium may not be suitable;
does
it bind to ice, or similar?
Agreed. Aluminium is wrong. Its specific heat capacity is too small. Mild
steel is fine but, of course, will need rubbing down before each use.
