Love to be going Ian but we're away that same day. Short of selling the route plan. . . . .hmmm, now there's an idea . . . .and without giving anything away, you'll need a full tank, decent map of the area, compass (since you'll not have the time or patience to try and get round using satnav) , emergency rations just in case you do get lost (or should I say for when you get lost) and spare bottles to pee in - not many toilets en route Oh yes, a co-driver would be really really useful - if there's anyone travelling 3-up, kidnap'em Ian!
One final comment and thats Hugh has spent a lot of time over this, especially that route and I hope everyone enjoys themselves and appreciates it is only a fun day out and not some rally stage, although when you get out there, you might have second thoughts. Enjoy.
