The reason past safaris have been open to all comers was to keep the individual entry cost down, although right from the start in 97 BMW riders were given preference to a place on the ride and a marginal discount on the entry cost. I think though we are now at a stage where rides sponsored by BMW are going to be those where you must be on a BMW to participate and smaller, guided tours are going to be the norm in the future given some of the land access issues and health and safety nazis playing there silly games. There are enough BMW owners now who will pay for this type of adventuring and overseas interest is way high that it used to be.
