My best friend was a first responder for his towns VFD at the age of 17 while still in high school. Anything is possible! If you want to change things, do what you can now...volunteer around the station when it is manned and just ask a ton of questions from the people that are there. You'll pick up valuable information in the process. Bigger cities have a program called Fire Explorers. Basically like the boy scouts but for Law Enforcement and Fire. You might see what kinda of information you can get on it around Wichita Falls or other places.. Just a thought!
I was actually in the Law Enforcement Explorers when I was in high school. That's when I thought I was going to school for a degree in LE, but my ways have changed for now. But I did learn a lot from being in the explorers. And it looks good on a resume when you're first starting out.
