A Lot more than through any other activities. Even today most of the people/friends i made through 4x4 is the ones we talk to the most. Even old Grumpy.
This year I've met 1 family in particular whom we have become firm friends with, specifically through the membership of a local offroading group. So for that I'm pleased.
Sadly you also get a large amount of asshats in the 4x4 community...
