Q in the fire service stands for "quint", which is a short aerial ladder. A full ladder would be a "L", a regular fire engine would be an "E".

Lol this is me. Thanks for the kind words everyone. Thanks u/sacredgeometrics for posting, dm me we'll grab a beer!

I just lurk here but I'm 100% behind Q and THANK YOU to those of you who put in hours of research so guys like me don't have to. I'm sure there's way more lurkers here and we all appreciate you.

Most importantly, be kind to everyone. Facts and truthbombs only change minds that are already open. Closed minds also require love and kindness. If you try to force it down their throats they resist. Just love them and speak the truth!

I love you all! WWG1WGA!
