In reply to Superchop75:
Not surprisingly availability is important. I did 5 years in a local team, but when it became impossible to meet availability requirements, I chose to leave before the matter was raised. You can be the fittest mountain-god with top cas care skills; but turning up is the biggest contribution you can make.
Lots of other ways to be involved: body for SARDA; be a casualty or training; help to fund raise - just go and ask, I'm sure you would be welcome.
