I agree but don't agree, I agree vollies do it out of there heart, like me, being a volly FF.
But I disagree with paid part, i do it cause I want to be a paid EMT and I enjoy it, I would volunteer on one of my off days if I had a volly EMS close by.
I know many paid fire fighters or EMTS/medics doing it for money and would not dare go volly.
