Wahiba challenge, co driver required for tomorrow (Muscat)

Are there any men out there passionate for sand driving and are free this weekend??

My husband is taking part in the Wahiba Challenge (Google for description) this weekend and his co driver has just pulled out, two people in a car is mandatory.
He will be driving an off road Nissan Xterra and already has all the kit, all he needs is a second person.

It would be leaving Muscat tomorrow at 1pm and returning Friday late afternoon/evening.

Let me know if you are keen, this is short notice but I'm told it's a great adventure.

Thanks.
