Historic Hood River
I’m not sure if the volunteers are learning how to use fire extinguishers or if the station is hosting a fire extinguisher inspection/recharge session, but they seem to be enjoying themselves. Most of the extinguishers are “Fyer-Fyter” brand. You can read a lengthy history of the brand here.
The double bay garage doors tell me this was probably taken at the fire department building up on Wilson Street, rather than the main station downtown.
