There is a very useful article on the website now, aimed primarily at first time Co-drivers ahead of this weekend's Arnold Clark / Thistle Hotel Snowman Rally. This comprehensive guide was compiled by one of Scotland's, and the UK's, top Co-drivers. I just wanted a simple list, and I got this, but I am truly grateful. Sadly, the author wishes to remain anonymous - probably to stop others asking for similar favours.
Anyway, not only will it be useful for the newcomers, the old-timers could benefit and learn too!
