My favourite site is Norfolk Fire and Rescue as they report every incident and the website is updated every 30 minutes with new incidents. They also have a good section on their vehicle fleet and a page for each station with room for local input by the local crew. Mind you, I'm a bit biased as it was Norfolk who offered the post of senior technical officer (photographer) 20 odd years ago (after letting me write the job and person description!). Sadly, drastic house price rises in Norfolk prevented me taking the offer up.
I've visited Gloucestershire fire service. At the time (the 1980s) they were partners in a project building fire engines based on a Jeep chassis. They carried a small water tank but were capable of tackling 90% of the incidents in the brigade and because they were much smaller than the normal fire engine were more adept in the narrow country lanes. They used lay flat hose, the same sort you could buy for your garden sprinkler.
