Drove in late in fog. Tired and hurried to bed. Left fog lights on, van battery completely flat in morning (seperate leisure battery!). Not another soul about and a long walk to Cannick with no mobile reception here. Bit of faffing then decision to walk the planned route knowing mobile reception would be on the hills. Quite a brutal walk but reception at top of 2nd hill and run down to beat the breakdown truck (huge, and all I needed was a jump start). Thank you Green Flag! Embarrasing....
