Rodger,
Thank so much for your very considered reply, it's very much appreciated.
There were to many things happened at once, when I went into the woods, it became dark very quickly and very misty. The lighting I have is not enough for this type of driving. Also at the same time the route disappeared from my screen, so I wasn't 100% sure I was on the right track. So my thoughts weren't fully on what was in front of me. I realise now I should have stopped and taken a breath.
Your totally right, I have learned lots in just one day.
I'm going to have another go today, sticking to the route planned.
Many thanks.
G.
