Having driven to Lochaline the day before (8 1/2 hours, rain from Glasgow onwards!) today was my "Into to NAS course", even public schools could not boast teacher/students ratios like this I had 3 tutors running me through the course for me on my tod.
I'm going to be lazy here and point you to this post from last years blog for what it involved (what? I am blogging 2 days worth - 3 if you count me mentioning the drive up!).
