Ok I've considered all the responses....I'm disappointed with some of them...I'm not trying to create extra rules or extra unnecessary compliance...I just don't want a repeat of the incident....the comment that it just happens to the welly guys...think again....it could happen on ANY ORE trip, I have heard of incidents on other 4wd Club trips as well....and its no different to say leading an ORE trip into a river in flood and then getting flack for it a year later......to other clubs and the press, police and OSH there is no differentiation between assn and non assn members.
Leave the namecalling and bickering to yourself....concentrate on stopping this happening. would you prefer I just sit back and not do anything and hope it doesn't happen again...?
Some suggestions I have had....
- Create some inhouse ORE GUIDELINES (Note these are used as a guide ie not a rule....do you know the difference

or do I have to quote the dictionary for you) for safely mounting hooks. this can also be used by trip leaders (or people leading trips) to check hooks with.
- Run some informal trip planning / trip leading sessions for interested Welly guys.
- Run some informal Recovery training for the interested Welly guys.
- Contact anyone organising a Welly trip and give them the tripsheets and drivers briefing to use if they want and see if they are ok.
I don't see anyone else offering any other serious or practical suggestions.....
