I used to trail quite a bit back in the day (2008-2013).
Unfortunately (fortunately actually), now working all over the dodgy parts of West/North Africa. I get my 4x4ing in, believe you me. The little free time I get back home I just want to chill and be with the family.
But as someone has said earlier, the younger guys these days aren't into 4x4, heavy, fuel guzzling vehicles as much as the average dude was 10/15/20 years ago.
As for the guys that have 4x4s but don't do trails. Well, I've given my explanation. But I think for most people in SA at the moment, its a money thing. I was shocked the other day when I was back in SA, and to fill the Triton (mine doesn't have SS Ian

) cost me 17 buffaloes.
One day when I'm working back in SA, I'll join in outings again. Hope that day comes soon.
