Help me out with the volunteer fireman thing

[J.A.K.]

Don't get me wrong, anyone volunteering for the public good is commendable. It's just that every VF I've known is pretty much a tool with a scanner and emergency lights on their vehicle so they can get a front row seat to some mangled wreckage. Why not just be a fireman?

Anyone here a VF? If so, can you educate me to what your duties are?
