I'm surprised nobody has suggested fire stations as a category proposal. I'd like to see this category as I have been involved in the fire service for many years now.
Possible variables include (off the top of my head); paid/volunteer, number of trucks, EMS involvement, population served, etc. Just an idea.
If you like this category proposal, please post a reply and also I'd love to hear about new variables to be added in if the category gets approval.
