Top day out!
Met a fellow geocacher on the way to Brig O'Turk, saw some nice bits of the world I hadn't seen before, and got winched backwards from a track that had turned to chocolate pudding.
(For the record, although it was my 110 that got stuck, it wasn't me who stuck it there!)
Thanks to the man with the winch, whose name I neglected to ask. Naughty me.
