In reply to Flinticus:

When the trees were still there it was quite common to see people parking very low down the road and then walking up. Will be interesting to see what if any difference the felling makes in terms of iciness (ditto the felling around Lix Toll - the bit coming into the trees from the west has a reputation for prangs, possibly as much due to wet roads as icy ones, and the first section on the way to Killin now feels oddly exposed to the edge of the stumps and general brash).
Re the LnL itself, the lower part gets lots of black ice - possibly a combination of water-runoff plus melting then freezing because it faces south - while from the narrow rocky bit near the dam onwards it's drifted snow that is traditionally the problem, eg there was quite a bit there (although it looked passable with care) Thursday last week even though the main snowline was quite far up the hill. It can be quite an adventure in itself, as you say.
