I spent a sunny April afternoon with the Metrosketchers group at the Firefighters Hall & Museum in NE Minneapolis. What a treasure trove! You could easily spend years there capturing all of the fire engines, equipment, and memorabilia.

Ken Avidor and Roz already shared many of the Metrosketchers' drawings here and here. You can see more of them on the group's Facebook page.
I highly recommend taking an afternoon (or a dozen afternoons) to visit. Don't forget to bring your fire engine red paints and pencils.
