Re: 4x4 Training
Many people may not know that OEX is a leader in elite forces military off road training, and the extent of what can be taught is very extensive. If you've been to a few days of training, this is really the tip of the iceberg!
These guys get into anything you may encounter off road, from things like mechanical field fixes, to extreme self recovery. I suggest touching base directly with Bruce at OEX and asking his opinion of what you should consider. I don't think he would suggest something that wasn't a real value. I can also say that if you get the chance to take one of his guided trips, do it.
