Who knows how the human mind works — especially mine — for some reason I became interested in fire hydrants. As with many things there is far more to know than most people (me) realize.
For instance, there are ‘wet’ hydrants and ‘dry’ hydrants. The reason being, in cold climates hydrants would freeze if water is contained within them, so a valve below ground is used to keep the hydrant dry. In warmer climates that isn’t necessary, so the hydrant is filled with water all the time — and, all the working parts are above ground, making servicing the hydrant far easier.
So, a bicycle ride around town photographing fire hydrants ensued.

This Mueller hydrant in our neighborhood shows the date of manufacture (1947) and place (Chattanooga TN)
The valve and cap bolts are 5 sided to discourage unauthorized use
The hydrants at the FMC site proved inadequate, along with many many other hydrants and equipment when this happened in 2013.
