Happy 4th of July, my fellow Americans! I'm re-sharing this image from the paper "The timing of fireworks-caused wildfire ignitions during the 4th of July holiday season".

Have fun today, and keep your pagers on!

By popular demand, I've created the map showing the percentage of fire departments that consist of 100% volunteer firefighters. According to National Fire Department Registry, this excludes composite departments that may have some volunteers on the roster, but also some paid firefighters.

Most fire departments in the US rely at least partially on volunteers. It's interesting to see which states have the most volunteer departments, and to think about how many people are on-call right now.

Note: FEMA considers departments with 51% or more volunteer members to be "mostly volunteer". Data showing departments with 100% volunteer crews is available at the link below.
