Hi tomtom,
No need to join the club, you'll be welcome at the rally whether a member or not. Here in Scotland a lot of non-members turn up at events, just come and enjoy yourself.
I've been a member of the MZRC for about 20 years, but I doubt that I'll renew my membership. Really, if you own one of the later 4 strokes there's not that much in the club for you, it's geared more towards the earlier 2 strokes.
The Glencoe - Ft William - Torridon route is really superb, and the way I went last time. There is also the options of Perth - Inverness - Achnasheen, and Perth - Dalwhinnie - Spean Bridge. All superb routes and it gives you the option of going one way and returning another.
See you there,
Norman
