most small departments that rely on vols. are always interested in new members. While the by-laws of the dept. regulate the number of active members, they have fireman reserves.The main difference is the reserves do not get to vote in meetings.
there are also courses in the states that teach firefighting to volunteers. It cost money, but most of the time the department, county, city or local insurance agencys will help foot the bill. There is also training officers in the local departments that can train to help you get certification.
You will be welcomed on any department worth being a member of, just remember the benefits are self pride and being a part of your community. Just be prepared to start at the bottom, work odd hours, andnnot too much support from the citizens at large, but it is worth it....fullclip
